There are 24 hours in a day, so 9 hours of the day is 9/24.

To reduce this, you need to recognize that both 9 and 24 are divisible by 3: 9=3x3 and 24=8x3

If you divide both by 3, you’d get your answer of 3/8.

You should sleep 3/8 of the day, when you’re 10 to 17 years old.

What is the slope-intercept form equation of a line that has a slope of 1 and passes
Bogdan [553]

Answer:

y = 1x+14

Step-by-step explanation:

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 1x+b

Substitute the point into the equation

10 = -4+b

Add 4 to each side

10+4 = -4+b+4

14 = b

y = x+14

When Julio cracked open his piggy bank, he
jok3333 [9.3K]

Answer:

52 quarters, 42 dimes

Step-by-step explanation:

Let's call the number of quarters q, and the number of dimes d.

q+d=94

0.25q+0.1d=17.20

Subtract q from both sides of the first equation to isolate d:

d=94-q

0.25q+0.1(94-q)=17.20

0.25q+9.4-0.1q=17.20

0.15q=7.8

q=52

d=94-q=42

Hope this helps!
