Answer:
19 nickels and 5 pennies
Step-by-step explanation:
Let x nickels and y pennies
100 = 5x + y
x + y = 24
y = 24 - x
100 = 5x + 24 - x
4x = 76
x = 19
y = 24 - x = 24 - 19 = 5
Answer: y int: (0,9) x int: (3,0)
Step-by-step explanation:
In slope intercept form, the equation is y=-3x+9. In the formula y=mx+b, we know b is the y intercept, so our y int. is 9. To find our x intercept, we set y=0. So, 0=-3x+9=>3x=9=>x=3
Answer:
y = 50
Step-by-step explanation:
Firstly, let's make an equation. We know that when y is 15, x is 3. Or, in other words, y is 5 times what x is. Therefore we can use the equation, y = 5x.
Now, just plug x into the equation.
y = 5(10)
y = 50
Answer:
3/8 of the day
Step-by-step explanation:
A day is 24 hours
You spend 9 of them sleeping
The fraction you spend sleeping is
9/24
You can simplify the fraction by dividing the top and bottom by 3
9/3 = 3
24/3 = 8
3/8
