An aquarium is to be drained. The aquarium is shaped like a rectangular prism with length 40 in, width 22 in, and height 16 in. Suppose water is pumped out of the aquarium at a rate of 704 in per minute. If the aquarium starts completely full, how many minutes does it take
to empty the aquarium?

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
