Answers and Step-by-step explanations:
1. "Five more" means + 5, "3 times a number" means 3x (where x is the number). So: 3x + 5
2. "Twice a number" means 2x (where x is the number) and "the quotient of twice a number and 7" means we divide: 2x ÷ 7
3. "10 less than" means - 10 and "than a number" means x - 10 (where x is the number)
4. "The product" means we need to multiply and "the product of -6 and a number" is -6x (where x is the number).
5. "13 more" means + 13 and "13 more than a number" is x + 13 (where x is the number).
6. "25 less than" means - 25 and "one third of a number" means 1/3x (where x is the number). So: 1/3x - 25.
7. "The sum" means we need to add, "a number squared" means
(where x is the number), so: x^2 + 14.
8. This means each pound is $18, so: 18x (where x is the number of steaks).
