The statement below describes a situation in which opposite quantities combine to make 0. is the statement true or false?

a mountain biker gets halfway up a hill and realizes he forgot his water, so he returns to his starting point.

a: true
b: false

54

Step-by-step explanation:

First, take the number 200. we can remove 20, because they didn't go to the exams.

Secondly, we have to find 70% of 180. This can be done by doing some math.

Let's do this by using fractions. 70/100 * 180 = 126.

Third, we find the other 30% by doing the same equation.

30/100 * 180 = 54

(This is the part where you thank me, and give your opinions, and maybe "brainliest" answer. :D)
