Answer:

It would be option B

Step-by-step explanation:

They would save more money taking 30% off of the total of three then 10% off of each one.

For example:

If each pizza cost 10$

10% would mean 1 dollar off each pizza meaning three dollars saved in total.

If we did 3 pizzas for 30% off the original price with no discount is 30$ and with the discount is 21$.

That means you would save 9$ doing the 3 for 30% off.

Hope this helps

After the fraction x plus 1 all over 2 minus the fraction x plus 2 all over 3 x have been combined using the least common denomi
RoseWind [281]

If I've read this correctly, it looks like this.

\dfrac{(x + 1)}{2 - \dfrac{(x + 2)}{3x}}

If that is correct, then the first step is to put the top part of the denominator over 3x

\dfrac{(x + 1)}{\dfrac{6x - (x + 2)}{3x}} = \dfrac{(x + 1)}{\dfrac{5x -2}{3x}}

The next part is to flip a three tier fraction. I'm afraid I have to show what happens. My latex is not that strong.

What you get is

\dfrac{3x*(x + 1)}{(5x - 2)}

This is just about your final answer. You could write it as

\dfrac{3x^2 + 3x}{(5x - 2)}

Solve 4|x + 6| = 16
Galina-37 [17]

4 | x + 6 | = 16

Divide both sides by 4.

\bf{\dfrac{4|x+6|}{4}=\dfrac{16}{4}   }

\bf{|x+6|=4 }

Absolute value is solved.

\bf{|x+6|=4 }

We know either x + 6 = 4 or x + 6 = -4.

<u>                                                                        </u>

x + 6 = 4 (Possibility 1)

x + 6 - 6 = 4 - 6 (Subtract 6 from both sides)

x=−2

<u>                                                                        </u>

x + 6 = -4 (Possibility 2)

x + 6 - 6 = -4 - 6 (Subtract 6 from both sides)

x=-10

Solution:

x=−2 or x=−10
