Common Problems and Their Solutions in Unit 3
To illustrate the application of the answer key, here are some common problems from Unit 3 and their solutions:
1. Solving Equations
Problem: Solve for x in the equation: 3x + 4 = 19.
Solution:
1. Subtract 4 from both sides:
3x = 15
2. Divide by 3:
x = 5
Answer: x = 5
2. Ratios
Problem: If the ratio of cats to dogs is 3:4 and there are 12 cats, how many dogs are there?
Solution:
1. Set up the proportion:
3/4 = 12/dogs
2. Cross-multiply:
3 dogs = 4 12
3dogs = 48
3. Divide by 3:
dogs = 16
Answer: There are 16 dogs.
3. Percentages
Problem: A shirt originally costs $40. If it is on sale for 25% off, what is the sale price?
Solution:
1. Calculate the discount:
25% of $40 = 0.25 40 = $10
2. Subtract the discount from the original price:
Sale Price = $40 - $10 = $30
Answer: The sale price is $30.
4. Statistics
Problem: Find the mean of the following set of numbers: 4, 6, 8, 10, 12.
Solution:
1. Add the numbers:
4 + 6 + 8 + 10 + 12 = 40
2. Divide by the number of values (5):
Mean = 40 / 5 = 8
Answer: The mean is 8.
