kirill [66]

Answer:

Any multiple of 71 (i.e. 71, 142, 710, etc)

Step-by-step explanation:

Republicans = R

Democrats = D

Republicans that liked apple pie = 0.80R

Democrats liked eclairs = 0.55D

Republicans who liked apple pie that also liked eclairs = (0.80*0.20)R

If the number of Republicans who liked both desserts is equal to the number of Democrats who liked eclairs, then the following must be true:

(0.8*0.2)R=0.55D\\0.16R=0.55D\\16R=55D

Since the number of Republicans and Democrats must be integers, the least number of members possible is 71 (55+16).

Any value that is a multiple of 71 is a possible value for the number of members of the group

nasty-shy [4]

Answer:

m = -10 + 5p

5p − m - 5p = 10 - 5p

simplifiy:

-m = 10 - 5p

divide -1 to both sides

m = -10 + 5p

m = -10 + 5p
