PLZ HELP STUCK ON THIS QUESTION
daser333 [38]

Answer:

5

Step-by-step explanation:

4a + 6b = 24

6a - 12b = -6

Rewrite the first equation below. Divide both sides of the second equation by 2 and write below the first equation. Then add the equations.

      4a + 6b = 24

+     3a - 6b = -3

----------------------------

      7a         = 21

Divide both sides by 7.

a = 3

Now substitute 3 for a in the first equation and solve for b.

4a + 6b = 24

4(3) + 6b = 24

12 + 6b = 24

6b = 12

b = 2

a = 3, and b = 2

a + b = 3 + 2 = 5

A school holds classes from 8:00 a.m -2:00 p.m. For what percent of a 24- hour day does this school hold classes?
kati45 [8]
8:00 a.m all the way until 2:00 p.m.

8:00 a.m. to 12:00 p.m is 4 hours.
12:00 p.m. to 2:00 p.m is 2 hours

8:00 a.m. to 2:00 p.m. is 6 hours.

6 hours out of a 24 hour day.

\frac{6}{24} =\frac{x}{100}\\\\\frac{1}{4} =\frac{x}{100}\\\\\sf{Cross~multiplying}\\\\100 = 4x\\\\\sf{Divide~4~on~both~sides

\boxed{\bf{x =25}}

The school holds classes for 25% of the 24-hour day.
