Answer:
7.5 liters of a 40% sugat solution
Step-by-step explanation:
Let
x------> liters of a 40% sugar solution
remember that
40% = 40/100 = 0.40
60% = 60/100 = 0.60
56% = 56/100 = 0.56
we know that the amount of liters of a 40% sugar solution (x) multiplied by 0.40 plus the amount of liters of a 60% sugar solution (30 L) multiplied by 0.60 must be equal to the total amount of liters mixed (x+30) multiplied by 0.56
0.40x + 0.60(30) = 0.56 (x+30)
solve for x
0.40x + 18 = 0.56x +16.8
0.56x - 0.40x = 18 -16.8

The value from the set {10, 11, 12, 13} that makes the equation 2(x − 5) = 12 true is (blank).
Answer:
11
Step-by-step explanation:
Multiply the parenthesis
2*x = 2x
2*5 = 10
2x-10 = 12
Because we subtract 10 to get 12, we add 10 to see the 2x
12+10 = 22
Now 2x = 22
2x=22
2x / 2 = 22 / 2
x=11

Chris has finished 30% of an art project that has taken him a total of 9 hours so far. If he continues to work at the same rate, how many hours will it take for him to complete the entire project?
If Chris has finished 30% of an art project in 9 hours then he will take 30 hours to complete the whole work if he will work at same rate.
What is rate?A measure, quantity, or frequency, typically one measured against some other quantity or measure.
How to calculate time?Let the project contains 100 questions in total.
Chris finished 30% questions so he may finish 30 questions in 9 hours.
So in order to complete the 1 question he took =9/30 hours
In order to complete 100 questions he will take 9/30*100 hours which is equal to 30 hours.
Hence Chris will take 30 hours to complete the project.

Keisha has 45 coins in her piggy bank, consisting of only nickels, dimes and quarters. She has one fewer nickel than she has dimes, and one fewer quarter than three times her number of nickels. How many nickels does she have?
Answer:
20 nickels, 40 dimes, and 8 quarters
Step-by-step explanation:
This is a system of three equations with three unknowns. Let x = # of nickels, y = # of dimes, and z = # of quarters.
x + y + z = 68 (since there are 68 total coins)
.05x + .10y + .25z = 7
.10x + .05y + .25z = 6 (if the nickels were dimes and the dimes were nickels)
Multiply both sides of the last two equations by 100 to simplify, giving us:
5x + 10y + 25z = 700 or x + 2y + 5z = 140 if you divide both sides by 5.
10x + 5y + 25z = 600 OR 2x + y + 5z = 120 if you divide both sides by 5.
Let's solve the first equation for x. That gives us x = 68 - y - z. We can substitute this result into each of the final two equations to create a system of two equations with two unknowns, which is easier to solve. For the first equation:
(68 - y - z) + 2y + 5z = 140
68 + y + 4z = 140 or y + 4z = 72
For the second equation, we have:
2(68 - y - z) + y + 5z = 120
136 - 2y - 2z + y + 5z = 120
136 - y + 3z = 120
-y + 3z = -16
Now we have our system of two linear equations:
y + 4z = 72
-y + 3z = -16
If we add those two equations together, then we get 7z = 56 or z = 8. If z = 8, we can substitute this into either of the two previous equations. Let's choose the first. This gives us:
y + 4(8) = 72 or y + 32 = 72.
So y = 40. If y = 40 and z = 8, then we know:
x = 68 - y - z = 68 - 40 - 8 = 28 - 8 = 20.
Consequently, there were 20 nickels, 40 dimes, and 8 quarters in the piggy bank.
