Answer:

Yes because I can see people very sleep-deprived and even if 7 hours is not enough, it's better than 6. For the people who sleep 9 and a half hours, they have 1 more hour to get ready. The median is 8 which most likely means, most of the students will be able to sleep the recommended amount with the extra hour.

Solve for x.<br><br> 6x - 3 = 21 - 2x<br><br> (SHOW YOUR WORK)
patriot [66]

Answer:

Simplifying

6x + -3 = 21 + -2x

Reorder the terms:

-3 + 6x = 21 + -2x

Solving

-3 + 6x = 21 + -2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2x' to each side of the equation.

-3 + 6x + 2x = 21 + -2x + 2x

Combine like terms: 6x + 2x = 8x

-3 + 8x = 21 + -2x + 2x

Combine like terms: -2x + 2x = 0

-3 + 8x = 21 + 0

-3 + 8x = 21

Add '3' to each side of the equation.

-3 + 3 + 8x = 21 + 3

Combine like terms: -3 + 3 = 0

0 + 8x = 21 + 3

8x = 21 + 3

Combine like terms: 21 + 3 = 24

8x = 24

Divide each side by '8'.

x = 3

Simplifying

x = 3

PLEASE HELP !!!! ILL GIVE BRAINLIEST !!!
Marta_Voda [28]

Answer:

Hi it's down below! Hope it helps

Step-by-step explanation:

1) The angles are Supplementary

This is because both angles form 180°. The angle below angle "7x+9" is the same as 5x+3.  The angle above angle"5x+3" is the same as 7x+9.

2) They are both supplementary

They form 180°

3)180° = 12x+12°

4) Solving that:

180° - 12° = 12x

168° = 12x

x = 168°/12

x = 14°

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
