If you're looking for x then it would be x=18 since you add 13 to both sides to have x alone

A store has clearance items that have been marked down by 30%. They are having a sale, advertising an additional 60% off clearan

Schach [20]

Answer:

28%

Step-by-step explanation:

We get 30% off the original price

The new price is (100-30) = 70$ of the original price

Let x = the original price

The new price is .7x

Now get get an additional 60% off. We pay (100-60) = 40 percent of the price

Take .7x * .4

The new price is .7*.4 x

.28x

This is 28 percent of the original price x

If you assume the samples are representative how many whole wheat bagels might you infer are sold at each store

Alexxandr [17]

Maurine owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole wheat bagels are sold at each store each day. Shop A has total of 50 bagels in sample and 10 are whole wheat bagels. Store B has a total of 100 bagels in sample and 23 are whole wheat bagels. Shop C has 25 total bagels in sample and 7 are whole wheat bagels.

We find fraction of whole wheat bagels to the sample for each shop using given information

Shop A = $\frac{10}{50} = 0.20$

Shop B = $\frac{23}{100} = 0.23$

Shop C = $\frac{7}{25} = 0.28$

The number of whole wheat bagels for each shop that sells 500 bagels per day

Shop A = $0.20 * 500= 100$

Shop B = $0.23 * 500= 115$

Shop C = $0.28 * 500= 140$

Find the quotient of quantity of 4 times x to the 3rd power minus 12 times x to the 2nd power plus 8 times x all over negative 4

Readme [11.4K]

$\displaystyle \frac{4x^3-12x^2+8x}{-4x}=\frac{4x^3}{-4x}+\frac{-12x^2}{-4x}+\frac{8x}{-4x}\\\\=-x^2+3x-2$

This result corresponds to the first selection.

I need to know the answer

Lynna [10]

It would be 3/16.
In the previous post you had 54 which you didn't put into a fraction.

6x-3/2-3x=5/4-x-2
Which simplifies to:
4x-3/2=-3/4
4x=3/4
Turn the denominator to 16 by 4 and also multiply the top by 4 which becomes 12/16.
Divide the 12 by 4 and you get 3/16 which is the answer.
