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.

Answer:
Look below.
Sorry if the graph's aren't good.
Step-by-step explanation:
13) I'll attach a pic of my graphs:
Slope intercept form is y = mx + b
y = 2x + 1
m = 2
b = 1
14) y = 3/ 5x - 5
m = 3/5
b = -5
15) y = 1/4x - 8
m = 1/4
b = -8
