(1) 3x-2 +1=5 211
(2) 3x-2-1-1=52
(3) 3x - 2 = 4
3x-2 +2 = 4+2
.4 -
6.4
3x = 24
(8) 3x - 24
(9) x = 8

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

where is the figure

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
