Answer:
1. n=2
2. n=12
3. n=2
Step-by-step explanation:
1
12xy³/4xⁿy=3y²/x
12x²y³=12y³xⁿ (cross multiplied)
x²=xⁿ (cancelled out (12y³))
2=n
2
(-3a/2b⁴)³=-27a³/8bⁿ
-27a³/8b¹²=-27a³/8bⁿ (cubed left side)
-216a³bⁿ =-216a³b¹² (cross multiplied)
bⁿ=b¹² (cancelled out (-216a³))
n=12
3
(xy⁶/x⁵yⁿ)²=y⁸/x⁸
x²y¹²/x¹⁰y²ⁿ=y⁸/x⁸ (squared left side)
x²y¹²/x¹⁰y²yⁿ=y⁸/x⁸
y¹⁰/x⁸yⁿ=y⁸/x⁸ (simplified)
y¹⁰x⁸=x⁸yⁿy⁸ (cross multiplied)
y²=yⁿ (cancelled out (x⁸), simplified)
n=2

When a company makes 50 deliveries in 5 days, we can first determine the amount of deliveries in 1 day. This is 50 packages / 5 days = 10 packages per day. Hence, the company delivers 10 packages a day.
400 deliveries will therefore take them:
400 packages / 10 packages a day = 40 days
Hence, the anser is 40 days.
8(6) =48
-c would be 6 because you are subtracting -6 would you can change to a positive.
So the answer is 48+6=54
The answer is 54
