Answer: 
Step-by-step explanation:
What you are trying to do is isolate the variable x. For you to do that you have to first simplify the left side of the equation and then you solve for x.
Answer:
$68.97
Step-by-step explanation:
The equation you have to use is I=p(1.45)
If you have a 45% increase to 100, the original price was $68.97.
7 - 9w = - 29
Subtract 7 from both sides
- 9w = - 36
Divide by - 9 on both sides
w = 4
Anything in the negatives like -2*2=-4-1 = -5
Or positive values up to 5
2*5=10-1=9
Answer: Third option.
Step-by-step explanation:
By definition, the slope of a line can be calculated with the following formula:

Since you need to solve for
to find an equivalent expression, you can apply these steps:
1. You must multiply both sides of the equation by
:

2. Finally, you must add
to both sides of the equation:
