How high is the stack of the two books? novel and 3/4 inches and dicitonary 41/2
sergejj [24]
3/4 + 4 1/2 = 5 1/4

If you mean that the dictionary is 41/2 then the answer = 3/4 + 20 1/2 = 21 1/4. That's a big diction though and not likely measured correctly.

-22

Step-by-step explanation:

Due to order of operations rules, we must perform the subtraction inside parentheses first, getting:

Kevin bought 3 dvds for 45.99 how much would 7 dvds cost?
Alecsey [184]

Answer:

I am pretty sure the answer would be $107.31. Sorry if I'm wrong.

Step-by-step explanation:

First you take the total of the 3 DVD's (45.99) and you divide that by 3 (number of DVD's) to get 15.33 which is called the unit price. Then, you take your unit price and multiply that by how many items you are going to buy.

45.99 / 3 = 15.33

15.33 x 7 = 107.31
