Four players are to be selected from a 21-player baseball team to visit schools to support a summer reading program. in how many ways can this selection be made? ​

d. all of the above

step-by-step explanation:

x = 3

step-by-step explanation:

you haven't given us any choices but we can guess.

-35x = - 105       divide by - 35

-35x/-35 = -105/-35   the minus signs cancel out and 105 can be divided evenly by 35

x = 3

add 45+27=72

take 72 and subtract 180 since 3 numbers of a triangle equals 180.

180-72=108

the ansewer will be 108

im not sure but if i get this wrong let me know.
