If dean has 5 pencils 2 erasers 3 pens 12 markers 14 crayons

a. what is the ratio of crayons to erasers

b. what is the ratio to the total items to pens

Hey!

Ratios can be written as a fraction or something like a:b

The ratio between crayons to erasers:

24:2 or 24/2 (For every 12 crayons there will be 1 eraser)

The ratio between total items to pens:

5 + 2 + 3 + 12 + 24 = 45

45:3 or 45/3 (For every 15 items there will be 1 pen)

Hope This Helped! Good Luck!

14:2 and B. 36:3

Step-by-step explanation:

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,
