Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.
A pair of kids and a pair of adults decided to compete in a three-legged race. The kids got to
start 10 yards ahead of the adults, since they had shorter legs. When they were told to start,
the kids hobbled forward at a rate of 2 yards per second, and the adults hobbled after them
at a rate of 3 yards per second. Soon they were side-by-side. How long did that take? How
far did the adults go?

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

-1/2 +2

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

just get this app called photo math it should be able to do those
