An aquarium at sea world is 10ft long, 3ft wide, and is filled with water to a depth of 7ft. water weighs 62.4 pounds per cubic foot. a.) what is the volume of the water in the tank? b.) what is the weight of the water of the water in the tank?

the answer is simply just 6n add the two together as they have an n

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
