The amount of water in the mix is 2/(5+2) = 2/7 of the volume of the mix. That amount is ...
(2/7)(21 liters) = 6 liters
Then the other 21-6 = 15 liters are antifreeze.
A) To make the mix 1 : 1, 15-6 = 9 liters of water need to be added.

Hey there!
The range is the possible y-values of any function. That's the definition, but identifying range takes practice, so let me know if you need any help with that.
Hope this helps :)
Hi there!
Let's use x as our variable. We know that complementary angles add up to 90 degrees. So, angle 1 is equal to x. Then, we can figure out that angle 2 is equal to 2x - 15. Then, to solve for x, we need to set the value of angle 1 plug angle 2 equal to 90, since the angles are complementary.
WORK:
x + 2x - 15 = 90
3x - 15 = 90
3x = 105
x = 35
ANSWER:
x = 35
Hope this helps!! :)
