Subtract 81 then divide by that answer.
81+x=108
-81 -81

Answer: she needs 8 quart bottles.
Step-by-step explanation:
Ms. Monet is combining 15 cups of green paint with 15 cups of white paint. This means that the total number of cups containing the mixture of green and white paint us
15 + 15 = 30
1 Us liquid quart = 4 Us cups
x Us liquid quart = 30 Us cups
Cross multiplying,
4x = 30
x = 30/4 = 7.5 quarts of paint
Since she is pouring the paint mixture into empty quart bottles, the number of quart bottles that she needs is approximately 8

Answer: C is correct, No solution
Step-by-step explanation:
Let’s simplify the second equation,
8x-4y=-20
We can divide the whole equation by 4...
8x/4-4y/4=-20/4
Which becomes....
2x-y=-5
Now let’s move things around to see if it’s the same equation as the one on top...
-y=-2x-5
y=2x+5
Now we need to solve the systems...
y=2x-5
y=2x+5
Since their slopes are both 2 and their y-intercepts are not identical, the answer is no solution. The two lines will continue on without ever crossing because they have the same slope.
