Answer:
B) 36/(y+4)
Step-by-step explanation:
Use the process of elimination.
A cannot work because we are changing the operation. Instead of dividing thirty-six by the sum of four and a number, we are dividing thirty-six by four, then adding the unknown number. This is not the same as the original expression, so we know it is not this.
Next, check C. C doesn't seem right either. Remember that, unlike multiplication and addition, you cannot flip the order in which the operation is being done and still get the same answer. C says four plus a number divided by thirty-six, which is entirely different from our original expression. So the answer is not C.
And finally, check D. D doesn't work either. With D, we are dividing thirty-six by a number, then adding it to thirty-six divided by four. This is not the same as our original expression, so D isn't it.
That leaves us with B. Does it work? Yes, because changing the y and the four still will give the same thing. And yes, because 36 is being divided by the sum of that number and four. So it is our answer.

Answer:
It has to be a positive number.
Step-by-step explanation:
We have the equation:
So then we need to distribute -7p to the parentheses:
Then we need to set the equation equal to 0, so we must subtract 21 on both sides:
Then we need to factor this. So we end up with:
This is as much as this can be factored, so <u>we cannot go any further</u>.
Answer:
The coordinates of point S are (8,-2)
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
Let
Point S(x2,y2)
substitute the given values
<em>Solve for x2</em>
<em>Solve for y2</em>
therefore
The coordinates of point S are (8,-2)
