Question

what same number should be added to each one of the number 15,23, 29,44 to obtain number which are in ​

Answer 1

Answer:

property is looking like , a/b = c/d

let us assume the number which we have to add be x

15+x/23+x=29+x/44+x

(15+x) * (44+x) = (23+x) * (29+x). cross multiplication

simplified them

660 + 59x + x^2 = 667 + 52x + x^2

59x - 52x + x^2 - x^2 = 667-660

7x = 7

x=7/7

x=1

therefore the number would be added is 1
