Answer:
30 marbles would be green
Step-by-step explanation:
green chance is 0.3
red chance 0.7
.3 times 100
30 green marbles is what you would expect
If they have 11 boxes and 88 shorts there will be 8 shorts in each box
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
