Answer:
5
Step-by-step explanation:
-8x + 25 = -15
-25 = -40 then
-40 divide -8 to get 5
( C. ) m + 1 = 2
<u>Step-by-step</u><u> </u><u>explanation</u><u>:</u>
m + 1 = 2
⇒ m = 2 - 1
⇒ m = 1
The car was towed for 48 miles.
Step-by-step explanation:
Given,
Amount charges by Acme towing = $30
Per mile charges = $3
Total charged = $174
Let, x be the number of miles.
Towing charges + Per mile charges*number of miles = Total charged
30+3x=174
Subtracting 30 from both sides
![30-30+3x=174-30\\3x=144](https://tex.z-dn.net/?f=30-30%2B3x%3D174-30%5C%5C3x%3D144)
Dividing both sides by 3
![\frac{3x}{3}=\frac{144}{3}\\x=48](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B144%7D%7B3%7D%5C%5Cx%3D48)
The car was towed for 48 miles.
