Answer:

See below

Step-by-step explanation:

Let the number be n or m

1: The product of a number and 8÷4

  • n × 8÷4
  • product = multiplication

2: five times a number decreased by eight

  • 5×n - 8
  • times = multiplication, decrease = subtraction

3: The sum of the square of a number and a second number

  • n^2 +  m
  • sum = addition

4: three times the difference of a number and seven

  • 3×(n - 7)
  • times = multiplication, difference= subtraction

5: 9.85 less than the product of 37 and a number

  • 37×n - 9.85
  • product = multiplication, less = subtraction
