To find the unit rate, all we need to do is divide $22.68 by 12
22.68 ÷ 12 = 1.89
Therefore, each gallon of gas costs $1.89
Hope this helps you

Answer: 1=1 question 2 = 1 again 5-6 is the next and 4 3-10 5-6 next answer2-7 3-8 5-4 -22--9 2-29 are all the answers
Step-by-step explanation:
You add two equations together to eliminate a variable. This particular problem is nice, because it's already setup to eliminate X.
3x - 4y = 9
<span>-3x + 2y = 9
</span>
When we add these two together, 3x - 3x cancels each other out, leaving us with 0x, or nothing.
We continue with -4y + 2y (leaves us with -2y) and 9+9 (18).
-2y = 18
18/-2 = -9.
Now we have y = -9, and we can go back into the problems to solve for x.
<span>3x - 4(-9) = 9
</span>
3x + 36 = 9.
3x = -27
x = -9.
Confirm with the final equation:
-3(-9) + 2(-9) = 9
27 - 18 = 9
9 = 9 --- Confirmed.
Answer:
1
centimeters
Step-by-step explanation:
The diameter is equal to the radius × 2. We know that the radius is equal to 3/5 centimeters.
To solve this you must do
× 2.
This equals
, or 1
cm.
