Answer:
the answer for the operation that should be used to solve x+7 is -7
Answer:
x=2
Step-by-step explanation:
combine like terms= -7x -5x = -12x
-12x + 8 = -16
subtract 8 from both sides
-12x = -24
divide both sides by -12
x = 2
Answer:
The correct answer is: Option D: 8
Step-by-step explanation:
Given that she spent $208 on the sewing machines
And
the equation for profits to break even is:
208 + 10x = 36x
In order to find the number of purses to break even, we have to find the value of x
So,

Subtracting 10x from both sides

Dividing both sides by 26

The number of purses is 8
Hence,
The correct answer is: Option D: 8
