Agroup of 21 people went to the county fair with 9 people on a stagecoach and 3 people in each buggy. on the return trip 4 people rode in each buggy. how many people returned on the stagecoach

5 people

Step-by-step explanation:

21 people went to the fair and 9 people were on a stagecoach. The remaining 12 people rode the buggies. We know that 3 people were in each buggy, so there were 4 buggies (12÷3=4). On the return trip, 4 people rode each buggies, so there were a total of 16 people who rode buggies (4 people×4 buggies=16 people). The remaining 5 returned on a stagecoach (21-16=5).

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
