Answer:
11 bottles
Step-by-step explanation:
make a proportion because if you're using the same rate proportions can show that it's equal

divide the answer by 90 to find x
round to 11 because you can't have 10.8 bottles
Answer:
I know this is a bit late but it is 6 and 12
Step-by-step explanation:
if we use the formula b1 + b2 x h/ 2, u would do inverse operations. you multiply 2 on each side so that 72 would equal b1+b2xh and divide height on each side to get 18 is b1 + b2. if b1 is 2 times, it would be 2x + x is 3x and divide 3 on each side would give you 6 for x. If 6 is x, one side would be 6 and the other would be 12
