There are 28 students in a class. Sixteen of the students are men. What percent of the class are women? Round to the nearest tenth.

42.9%

Step-by-step explanation:

If 16 are men, this means 12 of the students are women (28 - 16 = 12)

So, 12 out of 28 are women = 12 ÷ 28 = 0.42857... = 42.857...% = 42.9%

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
