Answer: yes
Step-by-step explanation:
7 x - 5 = 8
7 x = 8 + 5
7 x = 13
x = 13/7
7 ( 13/7) - 5 = 8
91/7 - 35/7 = 56/7
56/7 = 56/7 = 8

Answer:
D. 30 kilometers
Step-by-step explanation:
Add all the given distances relative to the map together:
6.5 + 9.5 + 4 = 20
Multiply that by the scale to convert centimeters to kilometers:
20 x 1.5 = <u>30</u>
Your answer is 30 kilometers.
You also could have gotten the same answer by multiplying each number by the scale and then adding those together but that is slightly more work so the way I showed is more convenient.
