For this case we must simplify the following expression:
We apply distributive property:
To multiply powers of the same base, the same base is placed and the exponents are added.
We simplify similar terms:
Finally we have:

Answer:
3 full miles; anything less than 4 miles
Step-by-step explanation:
5 + 2.50x = 15
subtract 5 from both sides
2.50x = 10
divide both sides by 2.50
x = 4
4 miles is how long he can travel by spending all $15
Anything less will cost him less than $15
Answer:
The answer is m=-2 or m=7.
Step-by-step explanation:
The steps to solve this equation are below:
Factor: to get (m+2)(m−7)=0.
m+2=0 or m−7=0
m=−2 or m=7. So, your answer is m=-2 or m=7.
4. y= 1.5x-5 5. y=5/3x-4 6. y=4/3x-3 7. y=1/2x-5 8.y=-5x 9. y=-3/4x+10
