Question

Points R, S, and T are collinear, and S is between R and T. Find ST if RS = 6.4in and RT = 9.3 in.

Answer 1

Explanation:

The layout looks like this.

r-----------s-----------------t

6.4

----------------9.3-----------

Now you want st so the formula is

rt = rs + st

9.3 = 6.4 + st Subtract 6.4 from both sides

9.3 - 6.4 = st Combine

st = 2.9
