Answer:B
Step-by-step explanation:
Subtract the amount you have from the amount you need:
2 cups - 1 3/8 cups
Subtract the whole cup first:
2 cups -1 cup = 1 cup
8/8 = 1
Rewrite 1 as 8/8 then subtract the 3/8 you have:
8/8 - 3/8 = 5/8
You need 5/8 cup more
3x=4y
x+y=21
x = 21-y
3(21-y)=4y
63-3y=4y
63=7y
y=9
x+y=21
x+9=21
x=12
answer is (12, 9)
