Answer:
y = 2x + 6
Step-by-step explanation:
10x - 5y = -30
-5y = -10x - 30
y = 2x + 6
Ok so we know that x = y+70
So y+y+70 = 300
2y+70 = 300
2y = 230
y = 115
So we know that x = y+70
do x = 115+70
X= 185
It would cost you $187.20 to paint that

Answer:
1 7/8 cups leftover
Step-by-step explanation:
The total amt. of sugar Suze needs is 5(1 1/2 cups) = 15/2 cups, or 7.5 cups.

Thus, she has leftover the following amount: 9 3/8 - 7 4/8 cups, which
simplifies to 1 7/8 cups
