2x-y=-10
How you do this ?
Answer:
Maritza has not enough sugar to make the cookies.
Step-by-step explanation:
Missing data
The recipe requires 3 eggs for every 2 cups of sugar.
Maritza determined she would need 12 eggs.
Her mom bought 6 cups of sugar.
Writing data as a proportion gives
(3 eggs)/(2 cups of sugar) = (12 eggs)/(x cups of sugar)
Omitting units
3/2 = 12/x
Multiplying by x in both sides
3/2 *x = 12
Dividing by 3 and multiplying by 2 on both sides
x = 12*2/3
x = 8 cups of sugar
So, 6 cups are not enough.
