Answer: 3+7+9=19.....7/19=0.368 percent. Move the decimal two places to the right and round up for 37%
Step-by-step explanation:
Add all the colors together to get a TOTAL amount of ALL marbles.
The total amount for this problem is 19 (3+7+9=19)
The blue amount of marbles is given as 7.
Divide the blue amount (7) by the total amount (19) for the specific percentage for that color.
-6 = -3x -12
6 = -3x
x = -2
y = -3(-2) -12
y = 6 -12
y = -6
(-2,-6)
