1) This one's easy: q plus 8 is less than or equal to 15: q+8 ≤ 15
2) This one's a bit harder: The number 20 is no less than the difference of 4 times a number c and 8
- "No less than" means greater than or equal to ( ≥ ) So 20 is no less than means 20 ≥
- The difference ( a subtraction) of 4 times a number c and 8 is 4c - 8
Put them together and you get 20 ≥ 4c - 8
