20. In the 7th grade, there are 84 students who are either gymnasts or hockey
players. 24 of the students are gymnasts,
and the rest are hockey players.
Which statement is true?
A. For every 5 hockey players, there
are 2 gymnasts.
B. For every 5 gymnasts, there are 2
hockey players.
C. For every 7 hockey players, there
are 2 gymnasts.
D. For every 7 gymnasts, there are 5
hockey players.

A. For every 5 hockey players there is 2 gymnast's.

Step-by-step explanation:

So 24 students out of 84 are gymnast's.

To find how many hockey players there are you subtract 24 from 84.

84-24=60

So there is 60 Hockey players.

So now you go down the option choices and look which one is correct.

So the first choice says 5 hockey players for 2 gymnasts.

second choice 5 gymnast for every 2 hockey player. well we know that's wrong because you cant get to 24 counting by 5's. So B is not correct

C. 7 hockey players for every 2 gymnast well that one is also wrong because you cant get to 60 counting by 7's so C. is wrong

D. Is the same as C but switch soo we know that one is also wrong the last one left would be A.

5 hockey players for very 2 gymnast

so you count by 2s to see if you can get to 24 you can. It would take you 12 2 to get to 24 so we know thats right

Now we see if we can get to 60 counting by 5s we can so it will take you 12 5s to get 60 so we know Answer choice A is correct.

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

156 squared is the hypothenuse

so 156= c
