13 - 4 = 9
9/3 = 3
3 * 1 = 3
3 * 2 = 6
Answer:
Step-by-step explanation:
So we need to balance two things here. The overall volume, and the amount of hydrochloric acid.
Let's say x is the volume of the 12% solution and y is the volume of the 6% solution.
The sum of the volumes equals the total volume:
x + y = 24
And the sum of the amounts is the total amount:
0.12 x + 0.06 y = 0.09 (24)
We now have two equations and two variables. We can solve this system of equations with either substitution or elimination. Using substitution:
x = 24 - y
0.12 (24 - y) + 0.06 y = 0.09 (24)
2.88 - 0.12 y + 0.06 y = 2.16
0.72 = 0.06 y
y = 12
x = 24 - 12 = 12
So she needs to mix 12 ounces of 12% solution with 12 ounces of 6% solution to get 24 ounces of 9% solution.
Answer:
Step-by-step explanation:
Split the words at "and" and solve one piece at a time. (when a function has "or equal to", use the ones with the line under 
) Let x be the unknown value
"less than or equal to 87"
"greater than or equal to 83"
Put them together by putting x in the middle. Don't forget to make the signs face the right way:
Done.
