You have 24 homework problems for math class. You finish 12 of them during some extra time in class. If you complete 4 more problems while waiting for the bus, what fraction of the 24 problems will remain?

1/3.

Step-by-step explanation:

24-12-4=8

We have 8 problems left out of 24, so 8/24 is the faction we have then.

To simplify we must find the GCF (Greatest Common Factor,) which is 8.

We then divide each number by 8:

--->8/8=1

--->24/8=3

So then the fraction is 1/3.

Hope this helps. :)

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
