Answer:

x = 22, y = 20

Step-by-step explanation:

well 66 and 2x-22 are corresponding angles so those are congruent so you set that up like 2x - 22 = 66 to find x and for y 66 and 5y + 14 are supplementary angles so they equal 180 so you set that one up like (5y + 14)+ 66 = 180 and then its just basic math

A scientist mixes water (containing no salt) with a solution that contains 30% salt. She wants to obtain 180 ounces of a mixture

xxMikexx [17]

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.

So:

The amount of mixture will be:

$w + s = 180$

the amount of salt will be

$0w + 0.3s = 180 * 0.15$

$0.3s = 27$

$s = 90\ ounces$

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

$w + 90 = 180$

$w = 90\ ounces$
