Answer:
x=y
Step-by-step explanation:
-let x be the number of tennis balls and y the number of rackets.
-We divide the number of balls by the number of rackets to find out their ratio of proportionality:
![\frac{x}{y}=\frac{5}{5}=\frac{1}{1}\\\\\\=>x:y](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%3D%5Cfrac%7B5%7D%7B5%7D%3D%5Cfrac%7B1%7D%7B1%7D%5C%5C%5C%5C%5C%5C%3D%3Ex%3Ay)
-Hence, for each one tennis ball, there is a tennis racket.

Answer:
A
A
Step-by-step explanation:
Sorry if wrong
-7c+9=c+1 (subtract c on both sides)
-8c+9=1 (subtract 9 on both sides)
-8c=-8 (divide by -8 on both sides to get c by its self)
c=1
your answer is 1.
