Answer:

(a) x + y = 63 OR 3x = 63

(b) 21

Step-by-step explanation:

Let Vijay's age be x and Ajay's be y.

Ajay is twice as old as Vijay

==> Ajay's age = 2 × Vijay's age

==> y = 2x

Sum of their ages = 63

==> x + y = 63

Substituting 2x for y:

==> x + 2x = 63

==> 3x = 63

Solving the above-obtained equation:

==> x = 21

Ajay's age = 2 times that of Vijay

==> y = 2x

==> y = 2×21

==> y = 42

Find the distance from the point (4,2) to the point (0,1).

vagabundo [1.1K]

Answer:

4.123 units

Step-by-step explanation:

Data provided:

Coordinates of point 1 as ( 4 , 2)

and,

Coordinates of point 2 as ( 0 , 1 )

Now,

The distance between the two point whose coordinates are given is calculated using the formula as:

distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

on substituting the values, we get

distance = $\sqrt{(0-4)^2+(1-2)^2}$

distance = $\sqrt{(-4)^2+(-1)^2}$

distance = $\sqrt{16+1}$

Distance = √17 = 4.123 units
