Answer:
C. Dividing by 4 is the inverse of multiplying by 4.
Step-by-step explanation:
We have been given 4 options. We are asked to choose the option that represents inverse relationship.
We know that inverse of addition is subtraction and vice versa.
We also know that inverse of multiplication is division and inverse of division is multiplication.
Upon looking at our given choices, we can see that option C is the correct choice because we are multiplying and dividing by same number 4. Upon dividing and multiplying a quantity by 4, we will get the same quantity.

Therefore, dividing by 4 is the inverse of multiplying by 4.
-2y-4=4(y-1)
Always remove the pararentheses as your first step.
-2y-4 = 4y - 4
Combine like terms.
-2y - 4y = 4 - 4
-6y = 0
Divide both sides by -6 to find y.
-6y/-6 = 0/-6
y = 0
Done
Let’s assume the width of the floor is x and the area is a
To figure out the dimensions we need to figure out the value of the variable (x)
This means that the length is xm+32m (the m is for metres) and that the area is a>200m2
Because it says what is the possible dimensions let make the area 201m2
The formula for the area of a rectangle is length times width so the equation we use to figure out the value of x
201=x+x+32
So let’s collect like terms and solve from there
201=2x+32
201-32=2x+32-32
169=2x
169/2=2x/2
84.5=x
Now that we know the value of x is 84.5 we can figure out the length is 116.5m and the width is 84.5m
Therefore the dimensions of the floor is 116.5m by 84.5m
Yes the mean can have a remainder but the remainder would
normally be either rounded or converted into a fraction.
