The lemonade comes in 100% juice concentrate, but you only serve it as 70% solution.  unfortunately, one batch got overwatered, so you have 4 quarts of 50% solution.  how much 100% concentrate do you need to add in order to get the 70% solution?
how much of the 70% solution will you have?

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

answer: 1+1

step-by-step explanation: 1+1 is at least 2

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
