Agroup of 20 people from the retirement community is visiting the fair today. each person is between 75 and 79 years old and will participate in either the pie eating contest or the chili cookoff. if all 20 people joined the same event, how would the shape of the histogram change compared to the original?

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

they charge the same amount at 20 minutes.
