Answer:
You would need 18 quarts of sparkling water to mix with 9 quarts of grape juice
Step-by-step explanation:
1 1/2 ---------> 3/4
x --------------> 9
We clear the value of x:
x = ((9) / (3/4)) * (1 1/2)
Rewriting we have:
x = ((9) * (4/3)) * (1 1/2)
x = (36/3) * (1 1/2)
x = (12) * (1 1/2)
x = (12) * (3/2)
x = 18
50 out of 100 is half of the class; half of the circle will represent students going to college. 25 is a quarter of the class; a quarter of the circle will represent students not going to college. 25 is a quarter of the class; a quarter of the circle will represent students undecided about going to college.
The circle graph should look something like this:
Answer:
Part 1:
or 
Part 2: 
Step-by-step explanation:
To start things off, you must put everything on the opposite side of y so that you only have the y variable left.
In this case, put x onto the other side, making it negative since it's flipped, so you get
(since the x is negative you're using subtraction from 11).
Next, divide both sides by 5 to make 5y into y:


Then in this case you turn y=f(x), but the system did it for you, so all you have to put is
.
For the second part you must replace x with 2 since you need to find f(2).

Your answer for part 2 is
.
Four tenths is expressed as .4
five thousandths is expressed as .005
the sum of these is .405 and divided by 2 (there are two numbers we added), we get .2025, that is the average
Answer:
-.8
Step-by-step explanation:
ok so if you divide -16 by 20 you will get -0.8
and if you divide 20 by -25 your answer also be -0.8
they are equal
