Let x gallons be the amount of pure antifreeze that should be added to the 30% solution to produce a solution that is 65% antifreeze. Then the total amount of antifreeze solution will be x+3 gallons.
There are 30% of pure antifreeze in 3 gallons of solution, then
3 gallons - 100%,
a gallons - 30%,
where a gallons is the amount of pure antifreeze in given solution.
Mathematically,

Now in new solution there will be x+0.9 gallons of pure antefreeze.
x+3 gallons - 100%,
x+0.9 - 65%
or

Answer: he should add 3 gallons of pure antifreeze.
The probability would be 39.9%
The given probability states that 39.9% of the 3 years olds are in daycare. Therefore, it would be obvious to assume that if you randomly selected a 3 year old, that would be the probability that he/she is in daycare.

Answer:
- (-6, 10)
- (-10, 9)
- (-11, -6)
- (-5, 1)
Step-by-step explanation:
<em>(x,y) → (x-8, y+4)</em>
1. (2, 6)
(2-8, 6+4)
<u>(-</u><u>6, 10)</u>
2. (-2, 5)
(-2-8, 5+4)
<u>(-10, 9)</u>
3. (-3, -10)
(-3-8, -10+4)
<u>(-11, -6)</u>
ídk man u should connect it to <u>(11, -7)</u> since it's the only choice closest to the right answer, but If u can write the correct then write this. there's prolly an error in that quiz ídk
4. (3, -3)
(3-8, -3+4)
<u>(-5, 1)</u>
<u> </u>still not in the choices nanii but <u>(5, -14)</u> is the only choice left and also the closest, and even if u use calculator the correct answer is still (-5, 1). sigh, I hope this helper at least
