C) 22
D) 28

Answers

Answer 1

Answer:

A) 15

Step-by-step explanation:

PEMDAS

20 / 4 + (6 * 2) - 2

take out the parenthesis which is P

20 / 4 + 12 - 2

there is no E

the go the rest of the way MDAS

5 + 12 - 2

17 - 2

15

Answer 2

Answer:

15 (A)

Step-by-step explanation:

ok first off you have to remember PEDMAS parentheses,exponents,division.multiplication,addition.subtraction(D and M are from left to right, as well as A and S.)

so the first thing you have to do is 6*2 because it is in the parentheses

this equation turns into

20/4+12-2

now do the division

5+12-2

now you have to add because it is left to right (it doesn't really matter what you o first in this situation)

17-2

15 (A)

hope this helps! have a nice day :)

Figuring out ratios is pretty simple. Example: If the ratio of soccer balls to baseballs is 3:1 that means there are 3 soccer balls for every 1 baseball. Notice how it says “soccer balls to baseballs” and “3:1” the first type of ball/object is the subject for the 3 and the second ball/object is the number for the 1. So when it asks the ratio of chocolate cookies to the whole box, you need to put the number of chocolate cookies first (25) and the cookies in the whole box (40). So now the ratio is 25:40. Simplify and make it into fraction form and the answer is 5/8.
