Solve for x.
8x + 3 > 4 (1/2x – 3)

Step-by-step explanation:

So we have:

First, distribute the right:

Subtract 2x from both sides:

Subtract 3 from both sides:

Divide everything by 6:

Reduce:

And this is our answer :)

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
