Answer:
(-∞, -2)
Step-by-step explanation
You are writing it in inequality form instead of interval notation. The sign is also flipped so it should be y<-2 and then convert to interval notation which will give you the answer above.
Answer:
One number, let's call it x, is 6 more than twice the other number, let's say this number is y.
x= 2y+6
x+y=21
We're left with a system of equations.
If we substitute the first equation in the second we find the value of y.
(2y+6)+y=21
3y+6=21
3y=15
<u><em>y=5</em></u>
Now that we have found the value of y, we can take that value and substitute it in the second equation (since it's easier) to find the value of x.
x+ (5)=21
<u><em>x=16</em></u>
<u><em>Now to check if our answers are correct, we plug in both values into any equation and see if they equate.</em></u>
x+y=21
(16)+(5)=21
21=21
Our solution is correct!
A idk if that right but I slow so
8 quarts = 32 cups
So we have a ratio of 32 : 3/4 cups
And the equal ratio of 4: x
So to solve for x, divide 3/4 by 8.
3/4 divided by 8 = 3/4 •1/8 = 3/32 of a cup of green paint.
