Ten gallons of a 25% salt solution are to be obtained by mixing solutions that are 13% salt and 33% salt respectively. How many gallons of each are needed?

salt + salt = salt

0.13x +3.3-0.33x =2.5

-0.20x=-0.8

x= 4 gallons (amt of 13% solution to be mixed)

10-x= 6 gallons (amt of 33% solution to be mixed)

Step-by-step explanation:

the answer

b. they are parallel and will never intersect.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
