Sliva [168]

Answer:

Hi There!

Your answer is:

<u>Length = 116</u>

<u>Width = 56</u>

Step-by-step explanation:

L= 4+ 2w

Width=w

perimeter formula

l+l+w+w= perimeter

Subsitute L for 4+2w

(4+2w)+(4+2w) + (w) + (w) = 344

8 +4w+w+w = 344

8+ 6w = 344

-8

6w = 336

/6

w= 56

PLUG BACK IN!

Length = 4+ 2w

Length = 4+ 2(56)

<u>Length = 116</u>

<u>Width = 56</u>

CHECK YOUR WORK

116+116+56+56= 344???

344 = 344 YES

P + q = 1000 p is 150 greater than q calculate numbers p &amp; q
erma4kov [3.2K]
Because p is 150 greater than q we can substitute p like p = 150 + q. 
When we plug this in it looks like this
(150 + q) + q = 1000
subtract 150 from the left side
q + q = 850
2q = 850
divide 2 to get q alone
q = 425
