Question

Help Please !! I need someone to show me step by step ! The largest swimming pool in the world is in Casablanca. The rectangular pool has a perimeter of 1110 meters, and its length is 30 meters longer than 6 times its width. How many meters wide is it?

Answer 1

Hey can you help me ? :) @bigbrain446

Answer 2

Alrighty then let's get 'er done.

We want width right? Let's make width x

Answer 3

ok so the we would use this formula is p=2w+2l

Answer 4

yup yup! now plug in your jazz.

Answer 5

wait a mo though

Answer 6

we dont know length or width, but we know that length is 6 times the width plus 32

Answer 7

so what should L be instead?

Answer 8

(Maybe some variation of W?)

Answer 9

Am I making sense?

Answer 10

L= 6w+32

Answer 11

Right! So that can take the place of L in the earlier equation.

Also for simplicity it can be done like this 1/2p = w + (6w+30)
since you only need half the perimeter to find the length or width.

Answer 12

ok so how would i slove that now ?

Answer 13

W(6w) + w(30) ?

Answer 14

plug in the perimeter for p in the equation i mentioned

1/2p = w + (6w+30)

Answer 15

555=w+(6w+30)

Answer 16

??

Answer 17

Im so confused :(

Answer 18

Crud did I dig myself a hole? This should be making a whole lot of sense right about now

Answer 19

wow thats rude !

Answer 20

No no I mean I think I might have lead you down a wrong path

Answer 21

I'm really sorry I thought I knew what I was doing. I'll need a minute to figure it out <:/

Answer 22

need help im pretty sure i got it?

Answer 23

I started plugging numbers in and your answer is 75. Maybe we can work backwards from there.

Answer 24

w = 75
L = 6(75)+30
L = 480

Answer 25

no your doing it wrong

Answer 26

Show me how please

Answer 27

alright

Answer 28

since we know p=2l+2w,
and l=6w+30

Answer 29

when we add it up we get 14w+60=1110

Answer 30

so the answer is 75 :)

Answer 31

we subtract each side by 60 to get 14w=1050

Answer 32

then 1050 divide by 14

Answer 33

w=75 :)

Answer 34

Alright that makes sense. Sorry about the initial flimflam jackie
