Answer:
water : 90 ounces
salt solution: 90 ounces
Step-by-step explanation:
Call w the amount of water and call the solution containing 30% salt.
We want to get 180 ounces of a mixture with 15% salt.

The amount of mixture will be:

the amount of salt will be



Now we substitute the value of s in the first equation and solve for w


Answer:
y = -49 x = 69
Step-by-step explanation:
make an equation
x+y=20 and x-y=118
then you can solve by elimination
x+y=20
x-y=118
=2x=138
x=69
69-y=118
-y=49
y=-49
Those ratios are not equivalent because 240 divided by 16 is 15 and 560 divided by 28 is 20.
