Answer: The number is 15

Step-by-step explanation: basically the equation you should solve is

(x)+(2x)+(2x+7)=82

5x+7=82

5x= -7+82

5x=75

5/5x=75/5

x=15

Need help with number 8

Evgen [1.6K]

The slope-point formula of a line:

$y-y_1=m(x-x_1)$

We have:

$m=2,\ (-8,\ 1)\to x_1=-8,\ y_1=1$

Substitute:

$y-1=2(x-(-8))\\\\\boxed{y-1=2(x+8)}$
