Harold is a twice as old as jack , who is three years older than dan . if harold's age is five times dan's age, how old in years is jack ?

Answer

1 7/8 years                       or  1.875 years

Explanation

Let Jack's age be x years.

Then;

Harold = 2x years

Dan = 2x - 3

But Harolds age is thre times Dan's age.

∴ 2x = 5(2x -3)

   2x = 10x - 15

   2x - 10x = -15

    -8x = -15

     8x = 15

       x = 15/8

          = 1 7/8 years                       or  1.875 years

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
