Answer:

M=-1

Step-by-step explanation:

To solve -9-16m=7 need to us Inverse operations.

What is inverse operation?

Inverse operation is an operation subtraction, addition, division, or multiplication that undo's the given operation.

As showed as the image below.

so our goal is to isolate the variable.

A variable is a symbol in math a variable is some type of Letter in the alphabet.

Isolate the variable means (shown in the image below)

so first what we need to move is a number.

-16 is being multiplied by m

so easiest number to move at this point is -9 its being subtracted so we need to add 9 on both sides to move it.

after this we need to move -16m to move it we need to divide by -16

At this point m will be on one side.

and we need to simplify the left side.

these steps are shown in the image below once you are done

M will equal something.

once we simplify we get

m=-1

we want to plug it in to see if we are correct

as show in my steps in the image.

Cost of a CD: $23.50<br> Markup: 63%<br> Discount: 50%
Vedmedyk [2.9K]
Alright this equation has two big steps. First we need to find the price after it was marked up, then we need to take that number and find the discounted price.
To find the cost after a percent of it was added, we just need to multiply the two together and add.
=
$
23.50
+
(
$
23.50
⋅
(
63
%
100
)
)
(we divide by 100 to get the number out of a percent)
=
$
23.50
+
(
$
23.50
⋅
0.63
)
=
$
23.50
+
$
14.81
=
$
38.31
Ok now that we have the number after the price increase, we now need to find the final answer after a discount of
50
%
(do the exact same idea as above but switch the sign)
=
$
38.31
−
(
$
38.31
⋅
(
50
%
100
)
)
=
$
38.31
−
(
$
38.31
⋅
0.5
)
=
$
38.31
−
$
