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? Explain. (ANSWER BOTH)

Answer 1

5ft - 7.2ft +2.2 ft = 0

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

Explanation:

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.
