Agym instructer has a total of 60 hand weights in her studio. some of the hand weights are 3 pound weights and the rest are 5 pound weights. if their are 10 more 5-lb weights , than how many of each kind does she have?

Let's imagine that x is the number of 3 pound weights that the gym instructer has.

Since we know that there are 10 more 5 pound weights, which tells us that the number of 5 pound weight is x + 10, and the total amount is 60 hand weights, we have:

x + x + 10 = 60

2x            = 60 - 10

2x            = 50

x              = 50/2 = 25

So there are 25 3 pound weights at the gym.

From the number we have just found, we also know that the number of the 5 pound weights should be:

60 - 25 = 35 (hand weights)

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
