Question

Can someone help me with this?

Answer 1

ST=8.8

SR=15.5

Explanation:

ST is the difference between S and T.

that would be 16.3-7.5=8.8

similarly RT is the difference between S and R

That would be 7.5-(-8)=15.5.

Answer 2

ST = 8.8

SR = 15.5

Explanation:

As the question demonstrates, they're looking for the measure of ST - which means the distance from S to T.

Now to get ST you'll have to subtract the values given on the number line.

T = 16.3

S = 7.5

16.3 - 7.5 = 8.8

ST = 8.8

Moving on with SR, we have the following. We use the same method of differentiation.

S = 7.5

R = -8

7.5 - (-8) = 15.5

SR = 15.5
