  1. 10+2x is greater then or equal to 75
    this would be solved by subtracting 10 from 75 which would equal 65. This would leave your equation as 2x is greater then or equal to 75. Next you would divide 65 by 2 whuch equals 34.5 which you would then round up to 35. I hope I helped.

  3. 10+2d is greater than or equal to 75.
    This would be solved by subtracting 10 on both sides of the equation, resulting in 2d is greater than or equal to 65. You would then divide 2 on both sides and end up with d is greater than or equal to 32.5 which you would round up to 33. So it would take Peter 33 minimum days to at least spell 75 words.
