You have a system of linear equations. For solving this question, you can apply the addition method.

In this method, we try to cancel one of the variables x or y. Let`s go!

Now, you should replace the value found for x in any equation for finding y.

Answer

x=5 and y=-2

The product of 3 and a number x is 23 . What is the value of x?

Scrat [10]

I believed there's a typo in your question
The product of 3 and a number x is 2/3
if so
3x = 2/3
x = 2/3 * 1/3
x = 2/9

Find the diameter(s) of circle O.

schepotkina [342]

Answer:

The diameter of the circle O is 12 units

Step-by-step explanation:

There is no data in the image provided. To better help you, I'm assuming we have an arbitrary value of

$BC=6\sqrt{2}$

and the triangle B0C is right

Relations in the Circle

The diameter (D) is twice the radius (r) and the radius is the distance measured from the center of the circle to any point of the circumference.

Since the triangle B0C has a right angle, BD is the hypotenuse and 0B=0C=r

Applying Pythagoras's theorem:

$BC^2=r^2+r^2=2r^2$

Thus we have

$2r^2=(6\sqrt{2})^2$

$2r^2=72$

$r^2=36$

$r=6$

The diameter of the circle O is D=2(6) = 12 units
