Answer: x=66
explanation: x+(x-20)+(2x+10)+(x+40)=360
5x+30=360
5x=330
x=66
Cross multiply:
4 x 6 = 9x
24 = 9x
Divide both sides by 9
X = 24/9
X = 2.7 ( rounded to the nearest tenth)
Answer:
D. 6x-14
Step-by-step explanation:
So first we would do 3x^2+3x^2-5x^2
That would all cancel out so that would be 0.
Next we would do 3x-4x+7x, this would equal to 6x
Finally we would do -4-8-2, this would be equal to -14
Then the equation would be 6x-14
All you have to do is combine like terms.
Hope this helped!
Divide 3 on the numerator and denominator.
