Answer:
30cm x 72 cm
Step-by-step explanation:
The perimeter is the measurements of all sides added together. Let's start by dividing the perimeter by 2, so we have the sum of the length and width. This gives us 102cm. Let's call the width <em>x</em>, and the length <em>y</em>. We know <em>y</em> is <em>x</em> times 2 plus 12. (2x + 12) So, we know [x + y = x + (2x + 12)]. So let's solve.
x + y = x + (2x + 12)
102 = x + (2x + 12)
102 = 3x + 12
102 - 12 = 3x + 12 - 12
90 = 3x
90/3 = 3x/3
30 = x
The width is 30cm.

Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The original amount of money on the gift card was $45. After buying 8 cups of coffee, the remaining balance was $25.
<u>First, we need to calculate the unitary value of each cup of coffee:</u>
Unitary cost= 20/8= $2.5
<u>Now, we can structure the remaining balance formula (A):</u>
A= 45 - 2.5x
x= cup of coffee
<u>After 2 cups:</u>
A= 45 - 2.5*2
A= 40
