Okay, its actually pretty simple.

3v-9v

All we need to pay attention to is the 3 and the 9. It may actually be better if you write this as 3v + (-9v) just so it makes more sense.

If we add 3 to -9, we will get -6. So we have -6v = 30

We need to get v by itself to solve for it so if we were to divide both sides by -6, we would get v = -5

We can check this by plugging v into the first equation that you were given.

How to find MP when discount percent and SP are given

nadezda [96]

Given:

Consider the discount percent and SP are given.

To find:

The MP.

Solution:

Let x% be the discount percent Then

$SP=MP-x\%\text{ of }MP$

$SP=MP-\dfrac{x}{100}MP$

$SP=\left(1-\dfrac{x}{100}\right)MP$

$SP=\left(\dfrac{100-x}{100}\right)MP$

Multiply both sides by 100.

$100SP=(100-x)MP$

Divide both sides by $(100-x)$ .

$\dfrac{100}{100-x}SP=MP$

Therefore, the formula for MP is $MP=\dfrac{100}{100-x}SP$ , where x is the discount percentage.
