Answer:
C
Step-by-step explanation:
The best way to solve this is to transfer -217 to the other side. So add 217 to both sides
0 ≤ 7 + 217 - 28v Combine
0 ≤ 224 - 28v Now add 28v to both sides
28v ≤ 224 Divide by 28
28v/28≤224/28
v ≤ 8
You should have 2 questions on your mind.
- Why go to all the trouble of putting things on the opposite sides?
- What is the answer
1. You so all that trouble so that you don't have to switch the < to >. As long as you have the letter and its coefficient > 0, then you are going to be right.
2. The is v is less than or equal to 8. That's C
