Answer:

2 hours if they go to school.

10 hours if they dont go to school.

Step-by-step explanation:

add up the hours.

9/2+5/2=14/2=7hours +7 hour of sleep= 14 hours.

if they go to school for 8 hours then add 8. then it =22 hours witch gives you 2 hours

if they dont go to school then you got 24-14 hours=10 hours.

7/8 + (-2/3)
irakobra [83]

Ok, lets start with the top.

7/8 + (-2/3)

Thats equal to

7/8 - 2/3

The common denominator will be 24

21/24 - 16/24

Subtract

5/24

Now, to divide you multiply by the reciprocal, so

5/24 / 5/6

Becomes

5/24 * 6/5

Cross simplify and get your answer

1/4

avanturin [10]

Answer:

Step-by-step explanation:

1. Corresponding Angles

<1 and <5

<2 and <6

<3 and <7

<4 and <8

They are equal in measure because corresponding angles are always equal to each other which means that they are congruent.

2. Alternate Interior Angles

<3 and <6

<4 and <5

They are always equal to each other because alternate interior angles are always congruent.

3. They are alternate exterior angles which means that the angles are always congruent.

4. <8 will be 73 degrees which is the same as <4 because they are corresponding angles and they are always congruent.

5. Angle 6 will be 107 degrees because they are alternate interior angles and they are always congruent.
