The rectangle shown has a perimeter of 56 cm and the given area. Its length is 8 times more than three times its width. Write an
d solve a system of equations to find the dimensions of the rectangle.
1 answer:
Answer:
Dimensions of rectangle = <u>23 cm x 5 cm</u>
Step-by-step explanation:
<u>Equations we can form</u>
⇒ 2L + 2W = 56
⇒ L + W = 28
- Length is 8 more than 3 times its width
⇒ L = 3W + 8
<u>Substitute in previous equation</u>
⇒ 3W + 8 + W = 28
⇒ 4W = 20
⇒ W = <u>5 cm</u>
<u></u>
⇒ L = 28 - 5 = <u>23 cm</u>

y = -2x + 8
12 hours worth $87
1 hour would be $87/12 = $7.25
9 hours worth $65.25
1 hour would be $65.25/9 = $7.25
The constant of proportionality is $7.25 per hour.
