A math classroom has 30 students. The teacher assigned the students a project and told them they could turn it in on Monday, Tuesday, or Wednesday. 12 of the students turned the project in on Monday. 13 of the students turned the project in on Tuesday. The rest of the students turned the project in on Wednesday. How many students turned their project in on Wednesday?

The answer is 5

Step-by-step explanation:

We need to find out how many students turned in the project on Wednesday. In order to do this, this is what we need to do.

1. First we need to subtract 12 from 30 since 12 is how many students turned in the project on Monday.

2. 30 - 12 = 18

So now we have 18.

3. Next we need to subtract 13 from 18 since we know that 13 is how many students turned in the project on Tuesday.

4. 18 - 13 = 5

At the end we end up with 5.

So 5 students turned in the project on Wednesday.

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
