Perimeter of rec. = 2 ( l + w )

Given: perimeter of rectangle = 322m, length = 86m

Required: width = ?

Solution: 322 = 2 ( 86 + w )
Divide 322 by 2 ie, 322/2 = 86 + w
Will be equal to 161 = 86 + w
Therefore Width= 161 - 86 = 75

Just before her party starts, Jane fills a cooler with 80 cups of ice. She also starts filling glasses with ice, 0.8 cups each.

Fofino [41]

The equation that shows how the total number of cups of ice used, y, depends on the number of glasses filled, x, is $y = 0.8x + 80$

<h3>Linear function</h3>

Filling the cooler is an illustration of a linear function

A linear function is represented as: $y = mx + b$

Where

m represents the slope/rate
b represents the y-intercept/the initial value
x and y are the variables

<h3>The equations</h3>

By comparison, we have the following parameters

$m =0.8$ --- the amount of cups per ice
$b = 80$ ---- the initial amount of cup

So, the equation that represents this scenario is

$y = 0.8x + 80$
