The sum of 2 numbers is 48 and their difference is 24

Artemon [7]

Answer:

The numbers are 12 and 36

Step-by-step explanation:

x + y = 48

x - y = 24

Add y to both sides of the equation

x = 24 + y

Substitute new value for x into first equation

24 + y + y = 48

Add y's together

24 + 2y = 48

Subtract 24 from both sides of the equation

2y = 24

Divide both sides of the equation by 2

y = 12

48 - 12 = 36

The numbers are 12 and 36

Hope this helps :)

What’s the value of x?

ale4655 [162]

Answer:

x=12

Step-by-step explanation:

What we have here is a secant and tangent. Using this theorem,

Given the segments of a secant segment and a tangent segment which share an endpoint outside of a circle,

The product lengths of the secant segment and external secant segment equals the length of the tangent segment squared.

In other words,

$9(7 + 9) = {x}^{2}$

$9(16) = {x}^{2}$

$144 = {x}^{2}$

$x = 12$
