In the lab deandra has 2 solutions that contain alcohol and is mixing them with each other. solution a has 40% alcohol. solution b has 12%. he uses 1000 milliliters of solution a. how many milliliters of sol b does he use if the resulting mixture is a 32% alcohol solution

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

b.my answer is b.

brainliest

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
