Don't hate me if I'm wrong but I think the first one is 76 but I couldn't find out the second line.
Answer:
It takes <u>8 4/7 </u>days for both bricklayers to build the wall together.
Step-by-step explanation:
The first bricklayer takes 15 days to build the wall, which means it builds 1/15 of the wall per day.
The second bricklayer takes 20 days to build the wall, which means it builds 1/20 of the wall per day.
So if they build the wall together, the expression below will tell how much of the wall they build per day together.
1/15 + 1/20
To add the fractions, we must find a common denominator, which is 60.
4/60 + 3/60, which equals 7/60.
So, they can build 7/60 of the wall per day together. How many days will it take them? We must find how many times 7 fits into 60, which can be done by solving 60/7, which is 8 4/7.
So, it takes 8 4/7 days for both bricklayers to build the wall together.
Unlike terms I guess meaning a zero pair?
Answer:
3/4 or .75
Step-by-step explanation:
find two sets of coordinates on the grid. I choose 60,40 and 20,10. then first you subtract the y coordinates so 40 -10 which is 30 next you subtract the x coordinates so 60-20 which is 40 so your fraction is 30/40 which simplifies to 3/4 which as a decimal is .75
Answer:
No.
Step-by-step explanation: Assuming you mean x^3*x-7, these two equations do not produce the same line.
