Question

Use a system of equations to solve the word problem. A rectangular table has the perimeter of 18 feet. Its length is 5 feet greater than the width. Find the dimensions.

a) l =8, w =3
b) l =7, w =2
c) l =3, w =8
d) l =2, w =7

Answer 1

if it is a system then you need atleast 2 equations. the first equation will describe the perimeter, and the second will describe the dimensions in relationship to one another.

can you set up an equation for the perimeter that equals 18?

Answer 2

@zonazoo i dont have a pencil or paper on me, im doing this class on mobile right now :( i just needed answers

Answer 3

well if you are just looking for answers, then you should just work backwards...

take your answer choices and multiply both the l and w by 2, and add them up to see if you get 18... for example... in a) 2(8) + 2(3) = 22, which is not equal to 18, so a is not the answer... just repeat, for the other 3.

Answer 4

@zonazoo so its b? (:

Answer 5

yes, b/c in the second sentence it says l is 5 feet longer, so it is b. good job

Answer 6

thank you! (:
