Can anyone help me????

Answer:

Ed used 39/60 of one hour to complete his tasks.

Step-by-step explanation:

Find the least common denominator (LCD), which would be 20

Then, find how to get from 5 to 20 and 4 to 20.

Use division.

20/5 = 4, 20/4 = 5

After this, multiply the numerator to the according number.

2*4 = 8 = 8/20

1*5 = 5 = 5/20

Make the denominator 60 to represent 60 minutes in one hour

5/20*3/3 = 15/60

8/20*3/3 = 24/60

Add the two results.

15/60 + 24/60 = 39/60

Answer:

3x-1=8

Step-by-step explanation:What we need to do is to put 3 time a number which is 3x because the number is unknown. Next you would substract 3x by 1 which is going to be 3x-1. And lastly, 3x-1 would equal 8.
