The sum of two numbers is 30. Their difference is 12. Use substitution to solve a system of equations to solve for the two numbers.
Answer:
9 and 21
Step-by-step explanation:
setting up the equation
let x and y represent the two numbers
this means that x + y = 30
x - y = 12
using substitution to solve
if x - y = 12, that can be rearranged to x = y + 12.
substitute x = y + 12 into x + y = 30
you get (y + 12) + y = 30
simplify
2y + 12 = 30
2y = 18
y = 9
plug this into the original equation x + y = 30. this would be
x + 9 = 30
x = 21
the numbers are 21 and 9.

in essence it's just asking on getting the equation of that line in more or less slope-intercept form, hmmm well, it's a line, so all we need is two points to get it, hmmm let's see let's use the starting point and terminal point, so we know it goes through the origin, (0,0) and also goes through (1, 0.7), let's change 0.7 to a fraction, so its 7/10, ok, let's use those two points from it.

Answer:
[tex]\frac{17}{24}[/tex]
Step-by-step explanation:
Step 1 :
4 - 1 [tex]\frac{3}{5}[/tex] = 2 [tex]\frac{2}{5}[/tex]
Step 2 :
1 ÷ 2 [tex]\frac{2}{5}[/tex] = 1 × [tex]\frac{5}{12}[/tex] = [tex]\frac{5}{12}[/tex]
Step 3:
[tex]\frac{2}{3}[/tex] + [tex]\frac{5}{12}[/tex] = [tex]\frac{8+5}{12}[/tex] = [tex]\frac{13}{12}[/tex] = 1 [tex]\frac{1}{12}[/tex]
Step 4:
3 ÷ [tex]\frac{13}{12}[/tex] = 3 × [tex]\frac{12}{13}[/tex] = [tex]\frac{36}{13}[/tex] = 2 [tex]\frac{10}{13}[/tex]
Step 5:
1 - 2 [tex]\frac{10}{13}[/tex] = - 1 [tex]\frac{10}{13}[/tex] = - [tex]\frac{23}{13}[/tex]
Step 6:
1 - [tex]\frac{16}{39}[/tex] = [tex]\frac{23}{39}[/tex]
Step 7:
[tex]\frac{23}{39}[/tex] ÷ ( - [tex]\frac{23}{13}[/tex] ) = - [tex]\frac{23}{39}[/tex] × [tex]\frac{13}{23}[/tex] = - [tex]\frac{1}{3}[/tex]
Step 8:
[tex]\frac{3}{8}[/tex] - ( - [tex]\frac{1}{3}[/tex] ) = [tex]\frac{3}{8}[/tex] + [tex]\frac{1}{3}[/tex] = [tex]\frac{9+8}{24}[/tex] = [tex]\frac{17}{24}[/tex]

The cost of a bag of fruits is proportional to the number of pounds. The cost for 1 ⅕ pound of fruit is $6.54. How much does a pound of fruits cost? Write an equation based on your answer.
From the computation done, the cost of the pound of fruits based on the information will be $5.45.
From the information given, it's stated that the cost of a bag of fruits is proportional to the number of pounds and that cost for 1 ⅕ pound of fruit is $6.54.
Therefore, to calculate the cost of a pound of fruit, this will be:
= 6.54 / 1 ⅕
= 6.54 / 1.2
= $5.45
Therefore, the pound of fruits cost $5.45.

A system of equation may have one, zero or infinitely many solutions
The system of equation has no solutions
The systems of equation are given as:
[tex]y = -6x - 5[/tex]
[tex]-2y +7 = 12x[/tex]
Substitute -6x - 5 for y in [tex]-2y +7 = 12x[/tex]
[tex]-2(-6x - 5) +7 = 12x[/tex]
Open brackets
[tex]12x + 10 +7 = 12x[/tex]
[tex]12x + 17 = 12x[/tex]
Subtract 12x from both sides of the equation
[tex]17 = 0[/tex]

A rectangle’s perimeter is 86in . Its length is 9in longer than its width. Use an equation to find the rectangle’s length and width.
Answer:
Step-by-step explanation:
Let width be x
So length would be x + 9
If perimeter is 86, then
2(l+b) = 86
2(x + x+9) = 86
4x + 18 = 86
4x = 68
X = 17
Check:
2(x + x + 9) = 86
2(17 + 17 + 9) = 86
2(43) = 86
86 = 86

Frank rented a truck for one day. There was a base fee of $18.99, and there was an additional charge of 76 cents for cach mile driven. Frank had
S152.75 when he returned the truck. For how many miles did he drive the truck?
Answer:
Frank drove 176 miles.
Step-by-step explanation:
Subtract the base fee from the total payment
152.75 - 18.99 = 133.76
divide the remaining amount(price for miles driven) by the cost for each mile
133.76 / .76 = 176
176 miles.
On solving the linear equation in one variable, given that there was a base fee of $18.99, and there was an additional charge of 76 cents for each mile driven, Frank had $152.75 when he returned the truck, the number of miles driven were 176 miles.
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable.
Let the number of miles driven be x.
Given in the question,
base fees = $18.99
charge per mile = 76 cents = $0.76
The equation of the total cost becomes :
= base fees + charge per mile * number of miles
= 18.99 + 0.76x
Given the total cost = $152.75
Equating the two values,
= 18.99 + 0.76x = 152.75
= 0.76x = 133.76
= x = 176
