Sure, I will help you. The answer you are looking for is x=11.

Solution/Explanation:

Write out the equation:

3(x+5)=5x-7

Using the Distributive Property on the LEFT SIDE,

3x+15=5x-7

Next, subtracting 3x from both sides,

3x-3x+15=5x-3x-7

15=2x-7, or 2x-7=15

2x-7=15

Now, adding seven to both sides,

2x-7+7=15+7

2x=22

Finally, dividing both sides by 2,

So, therefore the final answer is x=11. And, also, the next step would be written as 3x+15=5x-7, as stated above, preliminarily.

I hope this helped you find your answer. Enjoy your day, and take care!

Solve pattern 66 73 13 21 52 _ 10 20

8090 [49]

The answer would be 61. First, if you are trying to figure out the pattern. You must subtract the second number with the first then fourth number with the fifth and so on, you get.

73 minus 66 equals 7.
21 minus 13 equals 8.
XX minus 52 equals x.
20 minus 10 equals 10.

Basing on the pattern of the set of numbers, x will equal 9, To get this you must do 52 and 9 which will equal 61.

Which undefined term is used to define an angle?<br><br> line<br> plane<br> point<br> ray

Afina-wow [57]

The Undefined term that is used to define an angle is a point.

<h2>Further Explanation: </h2><h3>Angle</h3>

An angle is defined as the union of two rays with a common endpoint.
The common end point is known as the vertex of the angle while the rays are known as the sides of the angle.

It is a part of a line with one end point and proceeds on in one direction.

<h3>Naming of angles</h3>

Angles can be named in three different ways;

Using three Capital letters such as ∠ PQR, or ∠BCD. The middle letter represents the vertex of the angle. Therefore, the angles above are read as "angle PQR" and angle BCD.
Using the Vertex of the angle. For example, in the case of ∠PQR, can also be called angle Q, while ∠BCD can be called angle C.
Angles can also be named by placing any number or symbol at the vertex in the interior of the angle. Such that angles can be called angle 1 or angle 3 , or angle 5, and so on.

Angles are measured using a tool known as a protractor

<h3>Measuring of an angle using a protractor</h3>

To measure the angle, the mid-point of a protractor is placed on the vertex of the angle.
Then lining up one side of the angle with the zero line of the protractor.
Then read the degrees where the other side crosses the number scale.
