Answer:
x = 1
y = 10
Step-by-step explanation:
5x + y = 15
Step 1: Move 5x on the other side by subtracting it from both sides
y = 15 - 5x
2x + y = 12
Step 2: Move 2x on the other side by subtracting it from both sides
y = 12 - 2x
Since y = y, that means 15 - 5x = 12 - 2x
Step 3: Add 5x to both sides
15 = 12 + 3x
Step 4: Subtract 12 from both sides
3 = 3x
Step 5: Divide both sides by 3
x = 1
y = 12 - 2x
Step 6: Plug in 1 for x
y = 12 - 2(1)
Step 7: Multiply 2 by 1
y = 12 - 2
Step 8: Subtract 2 from 12
y = 10
Answer:
75 men spent 7 hours or more exercising.
Step-by-step explanation:
If you multiply 300 by 0.67, you get 201. That would be the amount of men. Multiply 300 by 0.37 to get 111, the amount of people who spent less than 7 hours exercising, and subtract it from the 201 men to get 90. Then, multiply 300 by 0.75 to get 225, the amount of women that spent 7 hours or more exercising, and subtract it from 300, which would result in an answer of 75. That's how many men spent 7 hours or more exercising.
Answer:
The correction option is option A.
Step-by-step explanation:
The first question is designed as per the norms and framing structure used for questions of the market survey. It clearly presents the objective of the question and is a proper way of asking about some a new service/product being offered.
The choice of words in the second question is not up to the norms of the survey question formation. The use of term "less than the cost of a daily cappuccino" predisposes the customer in giving a biased answer.
