A synchronized swim team makes different patterns in the water by joining their arms and legs. One swimmer begins the pattern. After
5 sec, two swimmers join. At 10 sec, two more join. At 15 sec, another two join the group. If this pattern contin- ues, how many swimmers will be in the group after 30 sec?

You are constructing a histogram for scores that range from 70 to 100 in whole points. frequencies range from 3 to 10; that is, every whole-point score between 60 and 100 occurs at least 3 times, and at least one score occurs 10 times. which of these would probably be the best range and size for the score intervals along the x-axis?

For what value of x does 4x = (1/8) x + 5?

Can someone me and do the problem plz so i can understand it more better
