W letter is two pairs of parallel lines
Answer:
- 15x² + 7x + 1
Step-by-step explanation:
Given
2x² - 9 - 17x² + 10 + 7x ← collect like terms
= (2x² - 17x² ) + 7x + 1
= - 15x² + 7x + 1
Step-by-step explanation:
4x=3x
2+4x=3x+2
4x-3x=2-2
1x=0
x=1/0
X=0
(i think the question given was incomplete but this waht i could do with the given statement)
You could set up a proportion to figure out the anwer. 15 hurdles/60%=X hurdles/100%. Cross multiply, 1500=60x. Divide by 60, 25=X=total amount of hurdles. Hope this helps!
