Answer:
25.
Step-by-step explanation:
We can write the expression as 10x + 2.5x where x is the tens digit.
So reversed we have 25x + x.
- and 25x + x - (10x + 2.5x) = 27
22.5x - 9x = 27
13.5x = 27
x = 2 and 2.5x = 5.
So the number is 25.
Answer:
Step-by-step explanation:
we know that
The Pythagorean Theorem states that in a right triangle
where
c is the greater side (the hypotenuse)
a and b are the legs
In this problem
Let
c=AB ---> distance from point A to point B
a ---> the difference of the x-coordinates both points
b ---> the difference of the y-coordinates both points
so
substitute
Answer:
20260275
Step-by-step explanation:
the question is same as selecting 4 things from 150 things
= C(150,4). (nCr formula)
=[150×149×148×147]÷[4×3×2×1]
= 49×75×149×37
= 20260275
