Answer:

(3x + 5) + (x +3) = 180 sum of angles on a

straight line

3x + 5 + x + 3 = 180

3x + x + 5 + 3 = 180

4x + 8 = 180

4x = 180 - 8

x = 172/4

x = 43

PQR = 3x + 5 = 3(43) + 5 = 129 + 5 = 134

Hi! :)

It sounds like you need to multiply this fraction.

$\frac{3}{8}$ *16=6

So, Marge used 6 total inches of tape.
