#5 has a typo, but is correct in principle.
The rest are ok, though I wonder why you used "w" to represent the # months in #10. If you used w for weeks, then you are wrong.

1. To represent the total number of apples George has, we can start with the initial 5 apples and add the number of apples his mother gave him. Let's call the number of apples his mother gave him "n". Therefore, the expression to represent the total number of apples George has would be 5 + n.
2. To express "four times as much as a number k", we simply multiply the number k by 4. Therefore, the expression would be 4k.
3. Michelle writes 15 pages in her journal each week, and on her birthday, she writes an extra 5 pages. To represent the number of pages Michelle has written for any given week this year, we can multiply the number of weeks (w) by 15 and add 5 for her birthday. Hence, the expression would be 15w + 5.
4. To represent "the product of 8 and the difference of a number and 12", we multiply 8 by the difference between the number (let's call it "n") and 12. So, the expression would be 8(n-12).
5. "The quotient of 80 and 4 squared" can be calculated by dividing 80 by the square of 4. The square of 4 is 16, so the expression would be (80/16).
6. To represent "10 less than a number", we subtract 10 from the number (let's call it "n"). Therefore, the expression would be n - 10.
7. "The product of a number g and 8" can be represented by multiplying the number g by 8. So, the expression would be 8g.
8. To represent "half the sum of 5 and a number b", we add 5 and the number b together, and then divide the sum by 2. Hence, the expression would be (5 + b)/2.
9. Marion is 3 years more than 5 times as old as Paula. Let's call Paula's age "x". To represent Marion's age, which is 3 years more than 5 times Paula's age, we multiply 5 by x and then add 3. So, the expression would be 5x + 3.
10. Bianca puts $10 in a savings account each month, and on her birthday, she adds an extra $20. To represent the amount she has saved this year, we multiply the number of months (w) by 10 and add 20 for her birthday. Thus, the expression would be 10w + 20.
