Answer:
I tried to answer but I still would like to know what doesn't make sense.
Considering the identity:
The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.
If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of .
Let's go back to the definition of function again:
A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.
Hope it helped you a bit.
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.
