You just take the number of the color of interest (green) and divide by total marbles
9/35 = 0.257 ~~ 25.7%
Answer:
/ Solve equation [2] for the variable y
[2] 7y = 12x + 17
[2] y = 12x/7 + 17/7
// Plug this in for variable y in equation [1]
[1] 9x - 2•(12x/7+17/7) = -3
[1] 39x/7 = 13/7
[1] 39x = 13
// Solve equation [1] for the variable x
[1] 39x = 13
[1] x = 1/3
// By now we know this much :
x = 1/3
y = 12x/7+17/7
// Use the x value to solve for y
y = (12/7)(1/3)+17/7 = 3
Solution :
{x,y} = {1/3,3}

Step-by-step explanation:
Alright so you have to do 50-10=40. 40/5= 8. She has to run 8 miles for the rest of the month to meet her goal. If she runs more than 8 hours, she is past her goal. [(Don't mind this- (50-10)/5=h)]
