You add 11 to both sides first!
i believe the answer is a
Answer:
Step-by-step explanation:
let x be apple juice and y be orange juice
12 = x + y
x = 12 - y
15 = 1x + 1.5y
x = 15 - 1.5y
set the equations as equal
12 - y = 15 - 1.5y
solve for y
12 + .5y = 15
.5y = 3
y = 6, you bought 6 bottles of orange juice
so, 12 = x + 6 , x = 6 , you bought 6 bottles of apple juice
5x+1y=76
x+y=20
x+y=20
-x -x
y=-x+20
5x+1y=76
5x+1(-x+20)=76
5x-x=56
4x=56
X=14
14+y=26
-14 on both sides
y= 12
So Addy got 14 multiple choice correct and 12 true/false questions correct.
