Answer:-7/4
Step-by-step explanation:
2(x-2)=6x+2-2(-2x-4)
Open brackets
2x-4=6x+2+4x+8
Collect like terms
-4-2-8=6x+4x-2x
-14=8x
Divide both sides by 8
-14/8=8x/8
-7/4=x
x=-7/4
Answer:
70%
Step-by-step explanation:
there are 20 total marbles and only 14 are not blue so 14/20 = 7/10 = 70%
The answer is 13 1/3 or 13.333333333
8 x 5/3 = 13 1/3
It would be B. "Regular" factoring without the quadratic formula can't be done. Completing the square will work easily since the coefficient on the squared term is a 1. I personally wouldn't graph this to find the solutions, although you could with and x/y chart to give you enough coordinates to plot the graph correctly.
16 but there are left over apples and pears... I don't know if this helps
