M=p=x
x/45=16/x
x^2=720
x=sqrt(720)
sqrt mean root
m= sqrt(720)
Simon is 13 years old
Let x be Simon's age
Thus 4 years ago his age was (x - 4) and 2 years from now his age is (x + 2)
Hence 5(x - 4) = 3(x + 2)
distributing both sides gives
5x-20 = 3x + 6
subtract 3x from both sides of the equation
5x - 3x - 20 = 6
2x - 20 = 6
add 20 to both sides
2x = 6 + 20 = 26
divide both sides by 2
x =
= 13

Hi!
-6+7x-6x = 3
-6+x = 3
x = 3+6
x = 9
Answer:
x = 9
If x = the number you are trying to find:


and when dividing by a fraction you can flip it and multiply instead:
60 * 6/5 = 72
The number is 72
