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

Answer:

Step-by-step 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
