Answer:
The volume of water in the fish tank is 4.5 cubic feet
see the explanation
Step-by-step explanation:
<u><em>The complete question is</em></u>
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
step 1
Find the volume of the fish tank
The volume of a rectangular prism ( fish tank) is equal to

substitute the given values

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

We need an equation for this, theres no 'formula' for doing this (ignoring the quadratic formula, as that is a long-winded way of factorising a quadratic equation)
What u can do is do 3/63=5/x. so u have to get x all by itself.
3/63=5/x
cross multiply
63×5 and 3×x
315=3x
divide by 3 to the number 315
ANSWER:105
X: # of pairs of socks; y: # of blouses
Then $2.99x+$12.99y=$43.92.
Y = 5x - 2
9y = -2x + 10
9y = 3x + 8
y = (3/9)x + 8/9
