To find the number we do the inverse of division, and that's multiplication. We multiply 8 x 5 x 3 to get 120, that's our number. So Fernando is thinking of the number 120, and we can prove that it's correct by dividing 120 / 3 then the result divide it by 5 and we get 8.

Simple, if you have the ending number as 8;

You divided it by 5. So go in reverse, and multiply by 5.

8*5=40

Then, do the same thing again, you divided it by 3, so multiply by 3.

40*3=120.

Thus, the number that Fernando gave to Maria is 120.

iren [92.7K]

Let , coordinate of points are P( h,k ).

Also , k = 3h + 1

Distance of P from origin :

d=\sqrt{h^2+k^2}

Distance of P from ( -3, 4 ) :

d=\sqrt{(h+3)^2+(k-4)^2}

Now , these distance are equal :

h^2+(3h+1)^2=(h+3)^2+(3h+1-4)^2\\\\h^2+(3h+1)^2=(h+3)^2+(3h-3)^2

Solving above equation , we get :

P=(\dfrac{16}{21},\dfrac{23}{7})

Hence , this is the required solution.
