A 20-gallon salt-water solution contains 15% pure salt. How much pure water should be added to it to produce a 10% solution?

Elanso [62]

15% of 20 gal = 0.15 * 20 gal = 3 gal, so the solution contains 3 gal of salt.

If we add x gal of water to the solution, we end up with (20 + x) gal of solution. We want the new mixture to have a concentration of 10%, or

10% of (20 + x) gal = 0.1 * (20 + x) gal = 2 + 0.1x gal

of salt.

The amount of salt in the tank hasn't changed. Solve for x :

2 + 0.1x = 3

0.1x = 1

x = 10 gal

Write and graph a system of inequalities that models the situation.

liubo4ka [24]

Answer:

The feasible region in the attached figure

Step-by-step explanation:

Let

x ----> the number of shirts

y ----> the number of pants

we know that

The cost of the shirts (number of shirts multiplied by the cost of one shirt) plus the cost of the pants (number of pants multiplied by the cost of one pant) must be less than or equal to $80

The inequality that represent this problem is

$5x+8y\leq 80$

using a graphing tool

The feasible region is the triangular shaded area

see the attached figure

Because x²+1 has an imaginary solution so you can’t find a value to put on the side for synthetic division
