The sum of two numbers is 77. The greater number is 5 more than the smaller number. Which equation can be used to solve for the smaller number?
(5 points)
Group of answer choices
x(x − 5) = 77
x + (x + 5) = 77
x − (x + 5) = 77
x(x + 5) = 77

Lena needs $50 to buy some notebooks. She had saved $2 and plans to work as a babysitter to earn $8 per hour. Which inequality shows the minimum number of hours, n, that Lena should work as a babysitter to earn enough to buy the notebooks?
(5 points)
Group of answer choices
8n ≤ 50 + 2, so n ≤ 6.5
2 + 8n ≥ 50, so n ≥ 6
2 + 8n ≤ 50, so n ≤ 6
8n ≥ 50 + 2, so n ≥ 6.5

To answer the questions:
1. Based on the survey, Park Q had the greatest percentage of blue butterflies.
2. To find out how many more students prefer math over science, we need to subtract the percentage of students who prefer science from the percentage who prefer math. We can find the number of students who prefer math by multiplying 0.65 by 80 (the total number of students surveyed). Similarly, we can find the number of students who prefer science by multiplying 0.15 by 80. 0.65 x 80 = 52 students prefer math, and 0.15 x 80 = 12 students prefer science. So, 52 - 12 = 40 more students prefer math over science.
3. To solve for x, we need an equation. However, there is no equation provided in the question.
4. The inequality that represents the number of t-shirts Sam can purchase is x ≤ 4. This is because he wants to spend the rest of his money on t-shirts, which means the cost of the jeans should be subtracted from the total amount of money he has.
5. To solve for the smaller number in the equation, we need an equation. However, there is no equation provided in the question.
6. To determine who stacked the most pizzas, we need to add up the fractions/percentages given for each person. Ronnie stacked 0.25, Mack stacked 9/40, Kim stacked 35%, and Ada stacked the remaining pizzas. Comparing all these, Kim stacked the most pizzas with 35%.
7. To find the minimum number of hours Lena should work as a babysitter to earn enough to buy the notebooks, we can set up an inequality. Since Lena has already saved $2 and plans to work for $8 per hour, the inequality is 8n ≥ 50 - 2. Simplifying this gives us 8n ≥ 48, so the minimum number of hours Lena should work is n ≥ 6.
8. To solve for x, we need an equation. However, there is no equation provided in the question.
Therefore, some of the questions cannot be answered due to missing information or incorrect question formatting.
