The problem has you solving 4x = 88 and the first step - which is the proper step - is to divide by 4 on both sides. What it does is the following:

--gets x alone on one side of the equation

--keeps the equation balanced because it's on both sides

--Undoes the multiplying. Dividing and multiplying are inverse, or, undoing operations. 4 and x are put together with multiplying - so we use dividing to take it apart.

The idea of using 4 because it's a factor is the wrong choice. If the equation were 5x = 88 and you divide by 4, you aren't getting a single 1x alone. So the "divide because it's a factor" choice is wrong.

Thus the upper left choice is NOT a good reason and is the best answer.

Dividing 4× by 4 isolates x on one side of the equation.

all they others is a good reason to divide by 4

hope it helps

Darla spent $120.37 on groceries in January, $108.45 in February, and $114.86 in March. What was the average monthly cost of Dar

kari74 [83]

In order to find an average, you have to add all the numbers and divide by the number of things you added.

120.37 + 108.45 + 114.86 = 343.68
343.68/3 = 114.56

She spent an average of $114.56 each month on groceries.

Solve the following quadratic equation by the square root method. (Y-9)^2=64

enot [183]

Hello!

To solve this, first perform the opposite operation for the last operation (on the left side) on both sides. The last operation of the left side is squaring. Therefore, square root both sides.

$(y - 9)^{2} = 64$

$y - 9 = ±\sqrt{64}$

$y - 9 = ±8$

Please note that you must include ±. This is because the square root of 64 can be either positive or negative, as a square of either a positive or negative number is positive.

Now, add 9 to both sides.

$y = 9±8$

There are 2 solutions from here. One comes from adding 8, and the other subtracting 8. Therefore, the two solutions are:

y = 9 + 8 = 17

y = 9 - 8 = 1

Therefore, your two solutions are 17 and 1.

Hope this helps!
