Solve for x. Need help please

19

Step-by-step explanation:

1. Both angles would probably add up to 180 degrees.

2. So rewrite this as an equation. (2x + 3) + (9x - 32) = 180

3. Add up like terms like 2x and 9x which would be 11x

4. Rewrite equation again for less confusion. 11x + 3 - 32 = 180

5. Combine like terms again. Like terms this time are 3 and 32

6. 3 - 32 which would be negative 29

7. Rewrite equation again for less confusion. 11x - 29 = 180

8. Add 29 to both sides of equation meaning add 29 to 180.

9. You're left with 11x = 209

10. Divide 209 by 11

11. Lastly you get 19.

I hope this helped and that it's right!

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
