an aquarium shaped like a rectangular prism has a length of 12 and a width of 11 inches and a height of 20 in the aquarium has been filled with water as shown below if the volume of the water in the aquarium is 2,244 cubic inches how high is the water level

answer:

Problem 3

Part A:  Distribute and Combine like terms

3(2x - 10y) + 15y - 6(3x - 8y)

6x - 30y + 15y - 18x + 48y

-12x + 33y

Part B:  Factor the expression ->  -12x + 33y

-12x + 33y

-3(4x - 11y)

Problem 4

Find if the table is proportional

In order to be proportional, the amount earned / number of lawns need to equal 15.

1/15 = 15

2/30 = 15

3/48 = 16

4/64 = 16

No, this table is not proportional because the first two times the lawn is mowed, that person earns $15, but the next two times that person earns $16.  Therefore, it is a not proportional table.
