Solve for y. y – (–19) = 25 a. –44 b. –6 c. 6 d. 44

1 answer:

6 0

Y - (-19) = 25

First, simplify your brackets. / Your problem should look like: $y + 19 = 25$
Second, subtract 19 from both sides. / Your problem should look like: $y = 25 - 19$
Third, subtract 25 - 19 to get 6. / Your problem should look like: $y = 6$

Answer: C) y = 6

A chemist mixes a 10% hydrogen peroxide solution with a 25% hydrogen peroxide solution to create 30 liters of a 15% hydrogen per

FromTheMoon [43]

Your two equations are at the top, in the box is what each variable represents. Below the box is total liters of the 15%, which is going to equal the total liters for 10% plus the total liters for 25%. Make your percentages into decimals. There’s a total of 30 liters so, x+y needs to equal 30. Isolate a variable, I chose y, you can do either or (isolating x would be more math). Y is going to equal 30-x, substitute that for the Y in the second equation, then you need to distribute 0.25 into 30-x. Then it’s simple math, subtract 7.50 from both sides, add like gets, divide both sides by -0.15, making x=20.
