the average of two numbers is 34. The second number is three times the first number. What are the two numbers?

zvonat [6]

Hey!To solve this problem, we need to set up two equations and use the system of equations to solve.

Let x be the first number.
Let y be the second number.

(x + y) ÷ 2 = 34
x = 3y

Now, we can use substitution to solve.

(3y + y) ÷ 2 = 34
4y ÷ 2 = 34
2y = 34
y = 17

Now, you plug the value of y in the equation to solve for x.

x = 3*17
x = 51
hope this helps!!

an ellipse has a center at the origin, a vertex along the major axis at (13, 0), and a focus at (12, 0). What is the equation of

yan [13]

Hi, as the elipce has a center at the origion and tha major distance is the axis

$\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$

But,

c = 12 Distance of focus

a = 13 -> Major distance

b = ? ->

But,

$\\ b^2 + c^2 = a^2
 \\ 
 \\ b^2 + 12^2 = 13^2
 \\ 
 \\ b^2 + 144 = 169
 \\ 
 \\ b^2 = 169 - 144
 \\ 
 \\ b^2 = 25
 \\ 
 \\ b = \sqrt{5} 
 \\ 
 \\ b = 5

$

Then,

$\\ \frac{x^2}{(13)^2} + \frac{y^2}{(5)^2} = 1
 \\ 
 \\ or
 \\ 
 \\ \frac{x^2}{169} + \frac{y^2}{25} = 1$
