Answer:
x=17 plz the brainliest!
Step-by-step explanation:
3x+39=90
3x+39-39=90-39
3x=51
\frac{3x}{3}=\frac{51}{3}
x=17
You are correct. The answer is choice C.
The other choices A, B, D have each side add up to 180 degrees either because the angles are a linear pair (adjacent and supplementary) or because the angles are same side interior angles. Same side interior angles are supplementary if a transversal line cuts through a pair of parallel lines as so happens in this diagram.
Just divide 100% by 80% and multiply that answer by 5. I'm pretty sure that's how you do it.
Answer:
2
Step-by-step explanation:
that is the least common denominator
Answer:
-9x^3+4x^2+5
Step-by-step explanation:
(6x^2 - 3 - 5x^3) - (4x^3 +2x^2 - 8)
distribute the minus sign
(6x^2 - 3 - 5x^3) - 4x^3 -2x^2 + 8
Combine like terms
-5x^3 -4x^3 +6x^2 - 2x^2 -3 +8
-9x^3+4x^2+5
