The last one: x/2=45; x = 90
the problem says: half of a number is 45.

let's use x to represent this number
we know that dividing by 2 halves a number, so, x/2 = 45

to get x alone, we multiply 2 by 2 to cancel it out. so, multiply by 2 on both sides

x/2 • 2 = 45 • 2

x = 90

hope this helped!

Why the area and the perimeter are not both multiplied by the same factor.
lina2011 [118]

The constant of proportionality is equal to 11.

<h3>Constant of Proportionality</h3>

The constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship. Other names for the constant of proportionality include the constant ratio, constant rate, unit rate, constant of variation, or even the rate of change.

In this question, the constant of proportionality is that value that doesn't change or represents the number of players while x represented the number of games they played.

The constant of proportionality can be solved mathematically as

y = 11x\\x = 2\\22 = 11(2)\\22 = 22\\

The constant of proportionality is the value that makes y = 11x and it is 11.
