Answer:
$.09 per inch
Step-by-step explanation:
1 foot = 12 inches
Multiply each side by 7
7 ft = 12*7 = 84 inches
Take the cost and divide by the number of inches
$7.56 / 84 inches
$.09 per inch
Step 1.)
7x + 7 * 4.
We need to expand this term by multiplying a term and an expression.
The following product distributive property will be used:
A(B+C) = AB + AC
Numerical factors in this term have been multiplied.
In our example, the resulting expression will consist of 2 terms:
the first term is a product of 7 and x
the second term is a product of 7 and 4.
7x + (7 * 4)
Numerical factors in this term have been multiplied.
Which equals:
7x + 28
Hope you understand this and it helps. Have a great evening!

Answer:
Step-by-step explanation:
Leah wants to earn at least 120 dollars a month and she has two job options. This is written as
5x + 8y > 120
She also can't work more than 20 hours, leading us to the second equation
x + y = 20
First we solve for one variable
y = 20 - x
then substitute it into the first equation
5x + 8(20 - x) = 120
Solve for x
5x + 160 - 8x = 120
3x = 40
x = 40/3
Then we solve for y
y = 20 - x
y = 20/3
x < 40/3
y > 20/3
B and D will not work because their x+y is greater than 20.
E will also not work because the value is less than 120
