"The perimeter of a swimming pool is 126 feet. The difference between the length (x) and width (y) of the pool is 39 feet. What

are the dimensions of the pool?"
I'm supposed to figure this out using substitution but I'm not sure how, and any help at all is appreciated!

So we know the perimeter of a rectangle is two lengths plus two widths. We can conclude that 2x+2y=126. It also tells us x-y=39. Then use substitution from there

Answer:

\theta=36.43^{\circ}

Step-by-step explanation:

Given that,

Base = 42

Perpendicular height = 31

We need to find the value of \theta. It can be calculated using trigonometry as follows :

\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})

Put all the values,

\theta=\tan^{-1}(\dfrac{31}{42})\\\\\theta=36.43^{\circ}

So, the value of \theta=36.43^{\circ}.

Simplify:- for y.<br><br> 2x + 3 y/4 = 5
Fudgin [204]
2x + 3y/4 = 5....multiply everything by 4
8x + 3y = 20
3y = -8x + 20
y = -8/3x + 20/3 or y = (-8x + 20) / 3
