Answer:
3.75
Step-by-step explanation:
Set up the following ratio:
2400 watt-hours 1 day
------------------------- = ----------
9000 watt-hours x days
Then do criss-cross-apple-sauce:
x*2400=9000*1
And then solve for x:
2400x=9000
x=9000/2400
x=3.75
A = 18
You need to
Multiply both sides of the equation
- 3/2 x (-2/3) x a = - 3/2 x - 12
Then simplify both sides
a = - 3/2 x 12
Simplify
-3/2 x -12
a = -3 x -6
Multiply -3 by -6
Answer: a = 18
First we know that a dozen is 12
so She makes 12×15 cookoes which is
180 cookies
so lets put it in an equation.
36 cookies = 1 cup butter
180 cookies = X
The criss cross method
36 X = 180 cup of butter (notice here that the cookie cancelled out)
dividing each side by 36 we get
5 cups of butter
Answer:
y=mx+b
y=0x+9
y=9
Step-by-step explanation:
After you add 2,500 to 5,000 and then multiply it by 25% you receive the amount $9,375
