If you can’t see it says “ which numbers from set
{0,1,2,3,4,5,6,7,8,9,10} if any will solve this equation?

2x + 3 = 3(x + 1) - x

A) {3}

B) {1,3}

C) {1,2,3}

D) all of them

5y

step-by-step explanation:

coins of silver or gold

step-by-step explanation:

the correct option is b

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.
