24. You need to get k alone. Add 11 to -20, so your problem ends up like -9 < k.
25. You again need to get the variable alone. Divide both sides by -6, so your answer is v is less than or equal to -9.
26. The problem includes a fraction. The easy way to get rid of fractions is to multiply both sides by the denominator. m/2 multiplied by 2 is m, 8 multiplied by 2 is 16. So the answer is 16 < m.
