You can set them equal to each other so -3x+4=4x-10 and then you add 3x and 10 on both sides and get7x=14 and then divided both sides by 7 and get x = 2 and check by plugging in and you get -2 for y on both so solution is x=2

I need help lollololol
USPshnik [31]

Answer & Step-by-step explanation:

37.

Linda walked 3/4 (or 75%) of a track which is 3.5 miles long

Multiply 0.75 by 3.5 to get 2.625 miles (or 2 and 5/8 miles)

38.

We need to multiply the 2 and 3/8 mile track by 2 and a half (2 and 0.5)

1/8 is 0.125  

2/8 is 0.25

3/8 is 0.375

The track is 2.375 miles long.

Multiply 2.375 by 2.5

The track will be 5.9375 miles long after 5 years ( or 5 and 15/16 miles)

It's D.
.
Why?
.
Ok, your variable is x.
.
x stands for WHAT( the VALUE ) that you want to find.
.
So, assume you know what x is.
.
Pretend it's 10 or like infinity or what-not.
.
So, x + $32.25 = $45.32.
.
But you don't know x.
.
But it's easy to find it.
.
Subtract $32.25 on both sides, and BOOM!!
.
Hope this helped!.
