Answer:

X= 21

Step-by-step explanation:

First you want to add alike terms which will get you 8x+1=22+7x. Next you want to get your x on one side so I subtracted 7x which you get x+1=22. Last you want to get rid  of your 1 to get x alone so you subtract 1 from both sides and you get x=21.

Answer:

<h2>x = 21</h2>

Step-by-step explanation:

3x + 1 + 5x = 7 + 15 + 7x          <em>combine like terms</em>

(3x + 5x) + 1 = (7 + 15) + 7x

8x + 1 = 22 + 7x             <em>subtract 1 from both sides</em>

8x = 21 + 7x             <em>subtract 7x from both sides</em>

x = 21

Maia mixed a batch of punch for the class party. Her recipe called for 4 2/5 cups
siniylev [52]
You just have to add all the amounts of the ingredients.
4 2/5 + 3 1/2 + 12 3/4

You can first add all the whole numbers
4 + 3 + 12 = 19

Then, you can add all the fractions
2/5 + 1/2 + 3/4

To add all the fractions, you have to use the LCD. The LCD is 20. So, divide 20 with the denominator of each fraction and multiply the result with the numerator. The denominator of all fractions would now be 20.

So,
(2x4 + 1x10 + 3x5) / 20
(8 + 10 + 15)/20
33/20

The answer is an improper fraction. We divide 33 by 20 and get the remainder.
33/20 = 1 13/20

We have a whole number of 1, we add this to the sum of the whole numbers we got earlier.
19 + 1 =20

Finally, we put together the whole number and the remainder (fraction)
20 13/20.

Therefore, the recipe can make 20 1-cup servings. The remaining 13/20 can't make a full-sized cup.

If two sides of a triangle are congruent, then the angles opposite those sides are also congruent. The converse of this statement is;

if two angles are congruent, then sides opposite those angles are congruent.
