Answer:
3 gallons
Step-by-step explanation:
2 hours = 4 *3/4 hours
3/4 * 4 = 12/4 = 3
Answer: Jim can lay 25 tiles per hour.
Step-by-step explanation:
Let be "x" Jim's rate and "y" Pete's rate.
We know that Jim completed half the floor in 4 hours, then:
And Pete completed the other half of the floor in 2 hours, then:
Since Jim completed half the floor and Pete completed the other half:
[Equation 1]
We also know that Pete can lay 25 more tiles per hour than Jim, then:
[Equation 2]
Then, we can substitute Equation 2 into Equation 1 and solve for "x":
Therefore, Jim can lay 25 tiles per hour.
A square has 4 equal sides, so it's 320/4. Each side is 80 cm.
Y=3x + 8.25

If you were to graph y=x it would look like if you took the x axis and rotated it 45 degrees counterclockwise with the center of rotation on the origin
basically, it switches x and y
a reflection is like a miror
a reflection across y=x in equation would be
y=3x^2+5x-2 reflected across the y=x axis (aka the identity line) would be
x=3y^2+5y-2
