1.5m + 2500mm + 850mm + 4.8m
= 6.3m + 3350mm
= 6.3m + 3.35m
= 9.65m
Third option is correct.
1 + 2 = 1^2 x 2
2 + 3 = 2^2 x 3
3 + 4 = 3^2 x 4
......
5 + 6 = 5^2 x 6 = 25 x 6 = 150
Same as geno's answer.
\(\dfrac{27}{5}+(-\dfrac{44}{5})\\\text{The 2 fractions are already of same denominator.}\\\therefore\text{ We will just add the numerators and keep the} \\\text{denominator same.} \\=\dfrac{27-44}{5}\\=-\dfrac{17}{5}\\=-3\dfrac{2}{5}\)
What Melody explained means x and y could be anything unless x times y = 1.
Example x = .5 and y = 2 is impossible because the right hand side will be undefined. That will become atan of an undefined number which makes it more complicated. Actually I think this thing I already complicated enough XD
x/y = 0/0
0x = 0y
0 = 0
x and y could be different numbers. Therefore this is undefined just as Melody and Guest#2 explained.
Better explanation on how mayazhanmath's method worked.
4 = 6 + x
4 - 6 = 6 + x - 6
-2 = x
x = -2
Therefore x is -2.
Just be careful that (I don't know whether your teacher want to do so or not.) variables like x and y must be placed at the left hand side of the equal sign.
Do anything you want. I bet 2554 won't be bigger than 2147483647?
Example: Add 'em all XD
A + B + C + D = E
Therefore A = E - B - C - D , B = E - A - C - D , C = E - A - B - D , D = E - A - B - C
0,3% of world population
≈ 0,3% x 70000000000
= 210000 people.
Use the syntax: sqrt(number)
\LaTeX\: \sqrt{number}
