Step-by-step explanation:
Let the sum of rupee be x
no of boys be y
then each boy get x/y
now if the no of boys increased by 10 each boy get x/(y+10) = (x/y)-1 => x/(y+10) = (x-y)/y .........(1)
now case 2nd if no of boys decrease by 15 each boy get x/(y-15)= (x/y) +3 => x/(y-15) = (x+3y)/y ...........(2)

Hi again!
I think I already answered this question - right ?
Ok whatever - the answer and the steps are still in my head~
x^3 - 4x² + 2x + 10 = x² - 5x - 3
Again, same thing
x^3 - 4x² + 2x + 10 -x² + 5x + 3 = 0
Now factorize
(x + 1)(x² - 6x + 13) = 0
Set factor equal to 0
x + 1 = 0 or x² - 6x + 13 = 0
x = -1
The correct option is : B
A+ Guaranteed!
Answer:
15 lbs and 6 oz
Step-by-step explanation:
11 + 3 = 14 11 + 11 = 22 Remember that 1 lb = 16 oz. so 22 oz = 1 lb and 6 oz. 14+1lb6oz = 15 lb 6 oz.
Answer:
A = 169π/4
Step-by-step explanation:
From these two given points we find the length of the diameter of this circle, using the Pythagorean Theorem:
d^2 = (8 - 3)^2 + (13 - 1)^2, or
d^2 = 25 + 144 = 169
Thus, the diameter, d, of this circle is √169, or 13.
The radius is thus 13/2 units.
The area formula is A = πr^2. Here the area is
A = π(169/4), or A = 169π/4
