Question

Jeremy is practicing some tricks on his skateboard. One trick takes him forward 5 feet, then he flips around and moves backwards 7.2 feet, then he moves forward again for 2.2 feet. A: What expression could be used to find how far Jeremy is from his starting position when he finishes the trick? B: How far from his starting point is he when he finishes the trick?

Answer 1

5-7.2+2.2=0 he is in the same place he started

Answer 2

Answer: 5ft - 7.2ft +2.2 ft = 0

When he finishes the trick he will be in the starting point.

Step-by-step explanation:

Hi, to write the expression we have to analyze the information given:

• Forward: 5 feet

• Backwards: 7.2 feet

• Forward: 2.2 feet

So, we simply have to sum the tricks that takes him forward and subtract the tricks that take him backwards.

Mathematically speaking:

• 5ft - 7.2ft +2.2 ft = 0

When he finishes the trick he will be in the starting point, because the expression equals 0.
