Answer:
m=-42
Step-by-step explanation:
hope this helps:)
Answer:
-42
Step-by-step explanation:
Subtract 11 from both sides making it 2m=-84
Divide 2 from both sides making the expression m=-42
Solve the equation for x:
-3(x + 4) + 5x = 24
[tex]-3(x + 4) + 5x = 24\\\\-3x - 12 + 5x = 24\\\\2x - 12 = 24\\\\2x = 36\\\\x = 18[/tex]
The solution for x in this equation is 18.

Step-by-step explanation:
Step 1: Define
-3(x + 4) + 5x = 24
Step 2: Solve for x
Distribute -3: -3x - 12 + 5x = 24Combine like terms: 2x - 12 = 24Isolate x term: 2x = 36Isolate x: x = 18Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -3(18 + 4) + 5(18) = 24Add: -3(22) + 5(18) = 24Multiply: -66 + 90 = 24Add: 24 = 24Here we see that 24 does indeed equal 24.
∴ x = 18 is the solution to the equation.

Find the surface area of this cylinder using pie.
Answer:
Thus, the surface area of a cylinder involving pie is:
[tex]\:\:\:A=36\pi \:[/tex] in²
or
[tex]A\approx 113.1[/tex] in²
Step-by-step explanation:
Given
radius = r = 2 in height = h = 7 inUsing the formula to determine the surface area of a cylinder:
[tex]A=2\pi \:rh+2\pi \:r^2[/tex]
[tex]A=\left(2\times \pi \times \:2\times 7\right)+\left(2\times \pi \times \:2^2\right)\:[/tex]
[tex]\:\:\:A=36\pi \:[/tex] in²
Thus, the surface area of a cylinder involving pie is:
[tex]\:\:\:A=36\pi \:[/tex] in²
or
[tex]A\approx 113.1[/tex] in²
A gift basket has 2 soaps and 5 lotions and costs $20. A second basket has 6 spas and 15 lotions and cost $60. Is it possible to determine the price of the soap?
A second basket has 6 spas--- I think you mean 6 soaps , so i will work with that
Answer:it is not possible to determine the price of the soap with the information given.
Step-by-step explanation:
Let s0ap be represented as x
and lotion be represented as y
2 soaps and 5 lotions costing $20 gives us equation 1 as
2 x+ 5y= 20-------- equation 1
second basket with 6 soaps and 15 lotions and costing $60 gives us equation 2 as
6x + 15y= 60------equation 2
Step 2 -- Solving
2 x+ 5y= 20-------- equation 1
6x + 15y= 60--------equation 2
BY elimination method, we multiply equation 1 by (3)
2x + 5y= 20 x (3)
6x + 15y=60-------equation 3
Subtraction of equation 3 from equation 2 gives us
6x + 15y=60-------equation 3
-6x + 15y= 60--------equation 2
0x +0y=0 which is no solution
Therefore it is not possible to determine the price of the soap

Answer:
J.)
Step-by-step explanation:
if you make there width to their length a ratio - like for the top you would do 8/2 - then the bottom is different. They all simplify to 4/1 except the bottom.
12/3 = 4/1
2/.5 = 4/1
10/2.5 = 4/1
10/4 = 5/2
The Vanderbloom family already traveled 200 miles on their vacation. The total distance that they will travel (d) is a function of their rate of travel (r) and their upcoming travel time (t). This is represented with the equation given below.
Answer: t=r/d-200
Step-by-step explanation:
d-200=r/t+200-200
t*(d-200)=r/t*t
t(d-200)/(d-200)=r/d-200
t=r/d-200

Give an example of an equation that has no solution equation and explain why it is a no solution equation.
Answer:
x = x + 7
Step-by-step explanation:
In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.
please solve for the correct answer. thank you! :)
Answer:
The first: y = -25x + 180Step-by-step explanation:
In every equation b = 170, so
The equation is y =mx + 170
On the line on the graph, for x=2 we have y = 120,so:
120 = m×2 + 170
-50 = 2m
m = 25
Therefore the equation is:
y = -25x + 180

Define the term rational number and give at least one example.
Answer:
A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero. Expressed as an equation, a rational number is a number. a/b, b≠0. where a and b are both integer
Step-by-step explanation:
All rational numbers are algebraic. ...
The quadratic surds (irrational roots of a quadratic polynomial ax2 + bx + c with integer coefficients a, b, and c) are algebraic numbers. ...
The constructible numbers are those numbers that can be constructed from a given unit length using straightedge and compass. ...
Answer:
A rational number can be divided by two integers

Find the slope and the y-intercept of the graph of the linear equation y=5/4x-7. The slope is ?, and the y-intercept is ?.
Answer:
Not Linear.
Step-by-step explanation:
Answer:
5/4 slope
-7 y intercept.
Step-by-step explanation:
The slope is the number in front of the x. The number in front of the x is 5/4. The slope is 5/4
1. The y intercept is whatever is behind the x or 0 if there is no number following the x.
2. The y intercept is also characterized by being on the same side of the equation as the x.
3. Finally it has no x in it.
In this case the y intercept is -7
Examples
y + 2 = x 2 is not the y intercept. subtract 2 from both sides. y = x - 2. Therefore -2 is the y intercept.
2y = 4x + 6 4 is not the slope. You have to divide by y = 2x+3. So 2 is the slope and 0,3 is the y intercept.

Answer:
4300 + 260d
Step-by-step explanation:
Given that :
Earning from Food booth cost :
Number of booth * cost
15(200 + 8d)
3000 + 120d
Earning from Game booth :
Number of booths * cost
20(65 + 7d)
1300 + 140d
Total sum :
Total earning from game booth and food booth
3000 + 120d + 1300 + 140d
3000 + 1300 + 120d + 140d

Answer:
40
Step-by-step explanation:
A kilometre is 1000 metres. 1000 / 25 = 40. So forty basketball courts would be approximately 1 km if lined up end to end.
The answer is 40 because 1 kilometer divided by 25 meters would be 40 and each court is 25 meters so that is 40 courts in 1 kilometer.

A coin collection consists of dimes and nickels. If there are a total of 500 coins valued
at $39. how many dimes are there?
Answer:
There are 280 dimes
Step-by-step explanation:
A nickel is worth 5 cents while a dime is worth 10 cents
Let n be number of nickel
d the number of dimes
n + d = 39
Secondly
$39 is same as 3900 cents
So we have;
10d + 5n = 3900
From first equation;
n = 500-d
Put this in second equation;
10d + 5(500-d) = 3900
10d + 2500-5d = 3900
5d = 3900-2500
5d = 1400
d = 1400/5
d = 280

Step-by-step explanation:
Two years ago, Jose bought $750 worth of stock in a cell phone company. Since then the value of his stock has been DECREASING at an average rate of 5 1/4 % per year. How much is the stock worth now?
Answer:
$671.25
Step-by-step explanation:
To get the amount by which the stock have reduced after 2 years, we will use the interest formula;
Interest = Principal * rate * time/100
Interest = 750*5 1/4 * 2/100
Interest = 750*21*2/400
Interest = $78.75
This means that the value of the stock has reduced by $78.75 after 2 years;
Amount that the stock worth now = $750 - $78.75
Amount that the stock worth now = $671.25

In the sixth grade 3/7 of the students are boys and 5/8 of these boys are in Miss Jones class what fraction of the entire six grade class are the boys in Miss Jones class
Answer:
Think of the entire population of 6th graders here. 3/7 are boys and 4/7 are girls. 5/8 of these boys are in Ms. Jones' class; that fraction would be (5/8)(3/7), or 15/56. This 15/56 represents the fraction of the entire sixth grade class who are in Ms. Jones' class.

You missed 1 4questions on your math test and 3 out of 10 on your history test. In which class did you earn a higher percentage on your quiz?
Answer:
You got a higher score on your math test.
Step-by-step explanation:
100/10= 10 so 3/10 turns into 30/100 so if you got three wrong that’s 30 points off so you scored a 70%. While on the other test, 100/4=25 so each question is worth 25 points if you miss one you get a 75%. Making that higher score.
