My internet isn't very good, so I'm going to answer 1 page at a time. Here's the 1st one.
30. Add 3 to both sides for x is less than or equal to 10, so your answer is the third one.
31. Just solve for x by adding 1 to both sides. 7x=10, so now just divide both sides by 7 to get x by itself. x=10/7.
32. (xy)/2, because you have to multiply x kits by y beads, and splitting between two people means dividing by two (so your answer is the third option)
33. Initial: 10 weekly: $2/week so you have 2w+10, because every week he makes two and he started out with 10.
34: to solve this type of equation, get the variable by itself. Since you have 50t on one side, divide both by 50 for an answer of 5.
