Question

Vivian combined different amounts of white paint, blue paint, and green paint to make 145 milliliters (ml) of paint of a new shade. The amount of white paint was x ml. The amount of blue paint was 10 ml less than twice the amount of white paint, and the amount of green paint was half the amount of blue paint. This is represented in the equation below.
x + (2x – 10) + one half (2x – 10) = 145
What was the difference in the amounts of white paint and blue paint Vivian combined?


35 ml

45 ml

30 ml

40 ml

Answer 1

you should solve for x first

Answer 2

yeah i did..but i kept getting a wrong answer

Answer 3

x + 2x - 10 + 1/2(2x-10) = 145

x + 2x- 10 + x - 5 = 145
4x - 15 = 145
4x = 145 + 15
4x = 160

solve for x

Answer 4

is that what you got?

Answer 5

omg yes. but its wrong :/

Answer 6

what did you get for x?

Answer 7

70

Answer 8

70?

4x = 160

divide both sides by 4 to get x

Answer 9

or is it...
x + (2x-10) + 1/2(2x-10)=145
x+(2x-10)+(1x-5)=145
x+(3x-15)=145
4x-15=145
4x=160 x=40

Answer 10

x = 40 right
