Answer:
7. is 2 squared. I didn't show my work but I am very sure that's the answer.
Cost per bottle
6 pack is 3.79 so the cost per bottle is 3.79/6=$0.631666666666667 per bottle
9 pack is 4.50 so the cost per bottle is 4.50/9=$0.50 per bottle
12 pack is 6.89 so the cost per bottle is 6.89/12=$0.574166666667 per bottle
0.63>0.57>0.50
the one that costs the least per bottle is the 9 pack which costs $0.50 per bottle
I am assuming 28/0. The short answer is that it is infinity. (Or they may want undefined)
Here is a bit longer explination:
Let's start by taking 28/1, that gives 28. What about 28/0.5 that gives 56, and as we keep decreasing the denominator closer to zero then the quotient will become larger and larger. We we reach zero, the quotient becomes so large that it is considered infinity.
Answer:13.5
Step-by-step explanation: 6:9
9:?
divide both by 3 2:3
now multiple 4.5. 9:13.5
Answer:
a = 0.
Step-by-step explanation:
2(a - 4) = 2a - 8 + 4a
2a - 8 = 2a - 8 + 4a
2a - 2a - 4a = -8 + 8
-4a = 0
a = 0.
