Tickets to see a movie cost $5 for children and $8 for adults. the equation 5x + 8y = 80 represents the number of children (x) and adults (y) who can see the movie with $80. if no adults see the movie, how many children can see the movie with $80? a) 13 b) 16 c) 6 d) 10

Step-by-step explanation:

The answer is B.16

Since the equation is 5x+8y=80

There are no parents so it equation will turn into 5x+8(0)=80, AKA, 5x=80

Using algebra, 5x=80 will x=80/5

which is 16

Step-by-step explanation:

5x+8y=80

y=0

5x=80

x=8-0/5=16

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
