A number is a solution when it fits within the range of answers that the function generates.
Answer:
a. 28.8
Step-by-step explanation:
Using the theorem of similarity, the following equation can be generated:

Solve for x

Cross multiply


Divide both sides by 25
x = 28.8
Answer:
18b+12
Step-by-step explanation:
6x3=18,6x2=12 so it's 18b(keep the variable)+12
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of tennis balls
y ----> number of tennis rackets
we know that
To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets
In this problem we have

so

That means
The number of tennis balls is three-fifths times the number of tennis rackets
