The number of hours he worked in all (written in fraction form) is 
From the question,
Mario worked from 8:25 to 12:45 yesterday.
From 8:25 to 12:45 gives 4 hours 20 minutes
Also, from the question,
Today he will work from 11:20 to 3:10
From 11:20 to 3:10 gives 3 hours 50 minutes
To determine the number of hours he work in all, we will add the time spent working on the previous day to that of the current day. That is,
4 hours 20 minutes + 3 hours 50 minutes = 8 hours 10 minutes
Now, to put the answer in fraction form, we will convert 10 minutes to hours
NOTE: 60 minutes = 1 hour
∴ 10 minutes =
= 
∴ 8 hours 10 minutes = 
Hence, the number of hours he worked in all (written in fraction form) is

Each of the eggs is 3.5 and a dozen is 12
So, we multiply 12 by 3.5 to get 42 grams
The dozens of eggs is 42 grams.
Hope this helps!
He earns 1800 so, 3000 minus 1800 is 1200, if u set this up as a proportional relationship you'll get 1200 = 3
x 100
cross multiply the relationship, 1200 by 100 is 120,000, 3 by x is 3x, 3x=120,000 isolate the variable so you divide 3x by 3 and get 1x,
what you do to one side you have to do to the other
so 120,000 divide by 3 is 40,000. If max wants to earn at least 3000 this month he will have to sell at least 40,000 dollars in items
It is linear, this is what it looks like graphed
Answer: Yes!
Step-by-step explanation:
If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. In this example, that number is 3 (y = 3x), and is called the constant of proportionality. ... It is a positive number.
