Answer:
The drove the truck for 131 miles
Step-by-step explanation:
To get the number of miles travelled
Step 1: Subtract base fee from payment
133.65 - 20.99 = $112.66
If each mile costs 86 cents = $0.86
Step 2: Divide $112.66 by $0.86
112.66/0.86 = 131 miles
Multiplying gives us 3 x 5 = 15
10^2 x 10^5 = 10^7
So we get 15 x 10^7. However, we need to move the decimal point from 15.0 to 1.5:
1.5 x 10^8. The answer is A.
Emma wanted to buy some apples from the store. They each cost $0.5. If Emma paid $12.5 in total, how many apples did Emma buy?
= ![\frac{5}{7}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B7%7D%20%20)
Cross multiply. (7)(x) = (5)(x - 2)
7x = 5x - 10
Subtract 5x from both sides.
2x = -10
Divide both sides by 2.
x = -5
