Step-by-step explanation: 276%of 9 is 24.84
Question 1. Raquel sold 18 tickets since if you do 54-22-14 you would get 18
Question 2. 14+28= j since 14 is the number of beans his mother put in the bag and j is the total amount afterward
Question 3. The answer is 49, simply solve for x by subtracting 14 on both sides
Question 4. You can add 4 blocks to the right or take away 3 blocks from the left since they will then have an equal amount of blocks
Question 5. The answer is 27.6, like question 3 solve for x by subtracting 8.6 on both sides
Question 6. The answer is $8.18, do this by subtracting 3.87 and 5.95 from 18 and the remainder would be the cost of the magazine
Answer:
You will need 220 mL of the 60% solution and 80 mL of pure alcohol.
Step-by-step explanation:
Let 'x' be the amount of 50% alcohol solution and y the amount of pure alcohol.
Therefore:
(0.5x + y)/300 = 0.65 ⇒ 0.5x + y = 190
x + y = 300
Solving the sistem of equations:
x = 220 and y = 080
Therefore, You will need
220 mL of the 60% solution
and 80 mL of pure alcohol.
