QuizQ2

The square of the first number is equal to three-fifths of the second number. Determine both numbers if you know that the second number is 5 times greater than the first, and neither of numbers is not equal to zero.

Correct result:

a =  3
b =  15

Solution:

a2=35b b=5a  a2=355a a2=3a a=3 b=5a=15a^2 = \dfrac35 b \ \\ b = 5a \ \\ \ \\ a^2 = \dfrac35 5a \ \\ a^2 = 3a \ \\ a = 3 \ \\ b = 5a = 15
