Step-by-step explanation:
A man by the name of Luigi Fonti wrote this. I hope it can guide you, as it did for me! "The set of rational numbers is closed for all the four operations, so x+y, x-y, x*y and x/y are rational too. And it is easy to demonstrate. A rational number can be expressed as a fraction of two integers. So, x can be expressed as a/b and y as c/d. Hence x+y = a/b + c/d = (ad+bc)/bd, which, as fraction of two integers, is rational."
Answer:
the first
Step-by-step explanation:
yes
Answer:
D or 3800
Step-by-step explanation:
Just divided 855 by 45 then multiplied 200 by 19
Please mark me brainlest
You add
1,813 + 1,513 + 761 = 4,087
Then you subtract
5,700 - 4,087 = 1,613
It's C. The standard deduction is $1,613 better than Chris's deductions
I just took the test.
Answer:
The slope is 0
Step-by-step explanation:
This is a horizontal line, and all horizontal lines have a slope of 0.
(to see why, just pick any two points, and work out the change in x over the change in y. i.e. rise/run. Since the y coordinates are all equal to 2, the numerator will be 2 -2, meaning the fraction is 0).
