You set it up as a y=mx+b problem 150=55x+40 then you subtract 40 from 150 making 110=55x so x=2

can you mark me brainlest?

Solve using the substitution method:<br><br>y = -2x - 7<br>y = 3x + 3

levacccp [35]

Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x

-5x-7= 3
+7. +7
-5x= 10

Divide -5 on both sides and you get x= -2

Then substitute -2 in the first equation

-2(-2)-7
4-7
Y= -3

Kevin, because he is going the fastest. He will take less time to get to the park than the others.

What are equivalent expressions for 6(y-1) and 64x+80

snow_tiger [21]

To find equivalent expressions, distribute the first one and factor the second one.

$6(y-1) \\ (6*y)+(6*-1) \\ 6y-6 \\ \\ 6(y-1)=6y-6 \\ \\ 64x+80 \\ 16( \frac{64}{16}x+ \frac{80}{16}) \\ 16(4x+5) \\ \\ 64x+80=16(4x+5)$
