Answer: option b.
Step-by-step explanation:
Based on the information given, you know that:
- The ground is at 0 feet.
- The initial posititions of both elevators were at 0 feet (because both moved from the ground level).
Therefore:
- If the final position of Elevator 1 is at +17 feet (positive) means that it moved 17 feet above the ground level.
- If the final position of Elevator 2 is at -22 feet (observe the negative sign) means that it moved 22 feet below the ground level.

Answer:
x = -117.6
Step-by-step explanation:
1/4x + 1/2 (3/4)x + 111 = x
1/4x + 3/8x + 111 = x
2/8x + 3/8x + 111 = x
5/8x + 111 = x
5/8x = -111
8/5 (5/8x= -111)
x = -117.6
Answer: 50
Step-by-step explanation:
You'll need to find one percent first:
12 ÷ 24= 0.5
0.5= 1% of the band
Now multiply one percent by 100:
0.5x100= 50
There are 50 students in the school band
