Iwill give you a brealeant

you don't have to to put 1,2 but you need to solve it to do 3

6 3/4

Step-by-step explanation:

 1. Use proportion:

8:4.5=24:x

8x=24*4.5

x=3*4.5

x=13.5

2. Use proportion

8:4.5=4:x

x8=18

x=18/8

x=9/4

x=2.25

3. For 24 people you need 13,5

for 12 people you need :

24:13.5=12:x

x=13.5/2

x=6.75

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
