Answer:

Step-by-step explanation:

$y = 3x \\ \frac{y}{3} = x \\ \\ \frac{3y}{3} + 2y = 45 \\ y + 2y = 45 \\ 3y = 45 \\ y = \frac{45}{3} \\ y = 15 \\ \\ x = \frac{y}{3} \\ = \frac{15}{3} \\ = 5$

The complete question is

Explain how you found the volume of water in the fish tank if it was only 1/2 full with water. Show your work and solution. Don't forget your UNITS!

You have a fish tank with the following dimensions:

Height: 3 feet

Width: 1.5 feet

Length: 2 feet

Find the volume of the fish tank

The volume of a rectangular prism ( fish tank) is equal to

$V=LWH$

substitute the given values

$V=(2)(1.5)(3)=9\ ft^3$

step 2

Find the volume of water in the fish tank

Remember that

The fish tank it was only one and a half full with water

Multiply the volume of the fish tank by one and a half to obtain the volume of water

$\frac{1}{2}(9)=4.5\ ft^3$
