42
Wtf👆
i dot freaking know
mike then cut off a 10-ft long piece of rope and a 1 yd long piece of rope.
what is the total length of these two pieces
of rope
let the 3 pieces have length:
3x, 5x, and 7x
3x + 5x + 7x = 33 3/4 inches = 135/4
15x = 135/4
x = 9/4
I will let you finish the rest, just 3 multiplications.
P=81 inches
Q= 135 inches
R=189 inches
