1

3

4

2

The equation is 3n + 5 = 14. To solve for n, we need to isolate the variable on one side of the equation. Subtracting 5 from both sides, we get 3n = 9. Dividing both sides by 3, we find that n = 3.

Explanation

The equation is 3n + 5 = 14. To solve for n, we need to isolate the variable on one side of the equation. Subtracting 5 from both sides, we get 3n = 9. Dividing both sides by 3, we find that n = 3.

6) Steve has x dollars in his bank account. He deposits $10 each week for 3 weeks. His bank balance now is $70. What is x? ( How much money did he have to start?)

$60

$20

$40

$50

Since Steve deposits $10 each week for 3 weeks, the total amount he deposits is $10 * 3 = $30. If his bank balance now is $70, then the initial amount he had in his bank account is $70 - $30 = $40. Therefore, x, which represents the initial amount of money Steve had, is $40.

Explanation

Since Steve deposits $10 each week for 3 weeks, the total amount he deposits is $10 * 3 = $30. If his bank balance now is $70, then the initial amount he had in his bank account is $70 - $30 = $40. Therefore, x, which represents the initial amount of money Steve had, is $40.

5

34

8

4

Sara and Kim have a total of 15 pencils, and Sara has 9 pencils. This means that Kim must have 15 - 9 = 6 pencils. Mark and Kim together have 10 pencils, so Mark must have 10 - 6 = 4 pencils.
