Answer:
c≤ 24/25
Step-by-step explanation:
"0.3" was replaced by "(3/10)". 2 more similar replacement(s). Simplify 3/10
61 3
(—— - ——) - (c + 1) ≥ 0 then simplify 61/10
10 10
3.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
61 - (3) 29
———————— = ——
10 5
29
—— - (c + 1) ≥ 0
5
4.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
c + 1 (c + 1) • 5
c + 1 = ————— = ———————————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Rewrite the whole as a fraction using 5 as the denominator :
c + 1 (c + 1) • 5
c + 1 = ————— = ———————————
1 5
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
29 - ((c+1) • 5) 24 - 5c
———————————————— = ———————
5 5
24 - 5c
——————— ≥ 0
5
Multiply both sides by 5
5.2 Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
5c-24 ≤ 0
5.3 Divide both sides by 5
c-(24/5) ≤ 0
5.4 Add 24/5 to both sides
c ≤ 24/5

Are (1, 1.5) and (12, 4) solutions to the equation? Why or why not?
Answer:
Step-by-step explanation:
plug in both values and see if the equations are true
1.5 = 1(1) + 5
1.5 = 1 + 5
1.5 does not equal 6
so (1,1.5) is not a solution
4 = 1(12) + 5
4 = 12 + 5
4 does not equal 17
so (12,4) is not a solution
Answer:
Just test the points in the equationPoint 1: (1,1.5)[tex]y=x+5\\(1.5)=(1)+5\\1.5=6[/tex] ?? Is that true? No, so this point is not a solutionPoint 2: (12,4)[tex]y=x+5\\(4)=12+5\\4=17[/tex] ?? Not true, its not a solution.so neither is a solution because the equation is not satisfieda triangle has side lengths of 14, 23, and 27. Is it a right angle ?
Answer:
No, it is not
Step-by-step explanation:
Here, we want to check if the lenghts given is that of a right angle triangle
For a right angle triangle, the square of the hypotenuse is equal to the sum of the squares of the two other sides
The hypotenuse represents the longest side
So 27^2 = 14^2 + 23^2
The difference between these is 4, and as such the triangle is not a right angled

How many solutions does the equation 4x + 8 = −2 − 2 + 5x have? (1 point) Two One None Infinitely many
Answer:
one
Step-by-step explanation:
only one value of x will let this equal. two would mean its exponential, none would mean the number before x would be the same on both sides but with different numbers for example 5x-8=5x+2. same 5x but when cancel them out -8 = 2 which is false. infinitely many means the two sides are identical.

What is 63.63 repeating as a fraction
Answer:
x = 700/11
Step-by-step explanation:
let x = 63.63...(by repeating i assume you mean the 63 is repeated as 63.636363...)
therefore 100x = 6363.63..
100x-x =6300 (the recurring bit has been cancelled out which is what you should always aim to do)
99x=6300
x = 6300/99
cancel down
x = 700/11
hope that helps! :)

Teresa measures five eighths foot of ribbon for a costume. She needs seven pieces of ribbon with that same length. What is the total length of ribbon Teresa needs to make all the costumes?
Answer:
[tex]Total\ Length = \frac{35}{8}\ ft[/tex]
Step-by-step explanation:
Given
[tex]Length = \frac{5}{8}\ ft[/tex]
[tex]Number = 7[/tex]
Required
Determine the total length
Since, he ribbons are of the same lengths.
The total length is calculated as:
[tex]Total\ Length = Length * Number[/tex]
[tex]Total\ Length = \frac{5}{8}\ ft * 7[/tex]
[tex]Total\ Length = \frac{5 * 7}{8}\ ft[/tex]

Which of the following lines is not parallel to the graph of y= 3x + 9
a.
3x - y = 10
c.
3y - x = 10
b.
y - 3x=11
d.
6x - 2y = 10
Please select the best answer from the choices provided
Answer:
a 3x - y = 10, b y - 3x=11, and d 6x - 2y = 10, are parallel.
Answer:
c. 3y - x = 10
Step-by-step explanation:
The slope-intercept form of a line
The equation of the line in the slope-intercept form is:
y = mx + b
Here, m the slope and b the y-intercept.
To compare the slope of different lines, we should write them in the above form and compare their values of m.
The given line is:
y = 3x + 9
The slope of this line is m=3
Any parallel line must have the very same value of m.
None of the following options can be directly compared because they are not in the slope-intercept form, so they must be converted.
a. 3x - y = 10
Solving for y:
- y = 10 -3x
y = 3x - 10
The slope of this line is m=3, thus this line is parallel to the given line
c. 3y - x = 10
Solving for y:
3y = x + 10
y = 1/3 x - 10
The slope of this line is m=1/3, thus this line is NOT parallel to the given line
b. y - 3x = 11
Solving for y:
y = 3x + 11
The slope of this line is m=3, thus this line is parallel to the given line
d. 6x - 2y = 10
Solving for y:
- 2y = -6x + 10
Dividing by -2:
y = 3x - 5
The slope of this line is m=3, thus this line is parallel to the given line
Answer: c. 3y - x = 10
1 inch : 12feet. if the actual width of the tent is 36 feet how wide is the tent.
Answer:
If the actual width is 36 feet, then the tent is 3 inches wide in scale.
Step-by-step explanation:
Let x be the width in inches.
The scale is: 1 inch : 12feet. The scale can be represented as inches to feet ratio and then equivalent ratios will be used
This can be expressed as fraction as 1/12
The equivalent ratios are:
[tex]\frac{1}{12} = \frac{x}{36}\\\frac{36}{12} = x\\x = 3[/tex]
Hence,
If the actual width is 36 feet, then the tent is 3 inches wide in scale.

Answer:
3.385137501
OR it is 1.909859317
Step-by-step explanation:
for the first one:
36/pi which is 11.4591559, then you take the square root of 11.4591559 to get 3.385137501
For the second:
you take the square root of 36 which is 6, then you divide 6 by pi which gets you 1.909859317

Aimee is in charge of buying tickets for a trip to the movies. She can buy tickets at the theater or online. At the theater, 8 tickets cost $60. Online, 6 tickets cost $51. Aimee needs to buy 24 tickets. How much money can Aimee save by buying tickets at the lower price? Show your work
Answer:
Aimee can save $24 by buying tickets at the lower price that is at the theater.
Step-by-step explanation:
First, you need to find the amount she would spent by buying tickets at the theater and online by using a rule of three:
Theater:
60→8
x ←24
x=(60*24)/8=180
Online:
51→6
x ←24
x=(51*24)/6=204
Now, you need to calculate the difference:
$204-$180=$24
According to this, the answer is that Aimee can save $24 by buying tickets at the lower price that is at the theater.
Answer:
Aimee can save $24 by buying tickets at the lower price that is at the theater.
a solution of x2 + 5x = −2
Answer:
You could solve this equation by referring to the quadratic equation
x=-5+/-√17/2
Step-by-step explanation:
The solutions to the equation f(x) = g(x) are -2 and 1. Iff and g are graphed on the same coordinate plane, which statement must be true?
The functions will intersect at x = -2 and x = 1.
The functions will intersect at y = -2 and y = 1.
Both functions will have y-intercepts at 2 and 1.
Both functions will have x-intercepts at -2 and 1.
Answer:
The correct option is;
The function will intersect at x = -2 and x = 1
Step-by-step explanation:
The question parameters are
The functions in the question are f(x) and g(x)
The solution to the equation f(x) = g(x) are -2, and 1
Given that the equations, f(x) and g(x), are both given in values of x, their solution will be the x values that satisfies both functions
Therefore, the functions will intersect (have the same values of f(x) and g(x)) at the points of the solutions, which are given as x = -2, and x = 1
The statement that should be true is the function will intersect at x = -2 and x = 1.
Given that,
The solutions to the equation f(x) = g(x) are -2 and 1. If f and g are graphed on the same coordinate plane.Based on the above information, the following information should be considered:
As the solutions represent x values that satisfied the both functions. Also, the functions should intersect that contains the same value i.e. x = -2 and x = 1.Therefore, we can conclude that the first option is correct.

Maggie sold 30 boxes of cookies in 6 days. How many days will it take her to sell 100 boxes of cookies?
Answer:
If maggie sold 30 boxes of cookies in 6days, how long will it take her to collect 100 boxes
10
Step-by-step explanation:
By Comparison:
100 ÷ 30 = 3.3333333333333
Then we must have:
x ÷ 6 = 3.3333333333333
Solving for x,
x = 6 × 3.3333333333333
x = 20
By Cross Product:
(30/6) = (100/x)
The Cross Product:
(30 * x) = (100 * 6)
Solving for x:
x = (100 * 6) / 30
Answer:
It will take her 20 days to sell 100 boxes of cookies.
Step-by-step explanation:
30 boxes = 6 days
100 boxes = [tex]\frac{100}{30}[/tex] × 6
= 20 days
