the sum of two numbers is 13 2 times the first number minus 3x and the second number is 1 if you let X stand for the first number and why for the second number what are the two numbers

Answers

Answer 1
Answer: If we let x be the first number and y be the second, we have (x + y) =13 and (2x - 3y) = 1. From the first equation, we have x = (13- y). Substituting this into the second one, we have 2(13 - y) - 3y = 1. Distributing the equation and re-arranging it, we now have (-5y) = (-26). Dividing both sides by -5, we have y = 5. Now x = (13 - y) = 8. Therefore, the two numbers are 5 and 8.

One centimeter = ________ millimeters.
A) 10
B) 0.10
C) 100
D) 0.01

Answers

Final Answer:

A) One centimeter = 10millimeters.

Explanation:

One centimeter is equal to 10 millimeters. This can be determined by using the conversion factor of 1 centimeter = 10 millimeters. To convert centimeters to millimeters, you simply multiply the value in centimeters by the conversion factor.

For example, if you have 5 centimeters, you can convert it to millimeters by multiplying 5 by 10, which equals 50 millimeters. Similarly, if you have 2 centimeters, you would multiply 2 by 10 to get 20 millimeters.

The conversion from centimeters to millimeters is straightforward and involves a simple multiplication by 10. This is because there are 10 millimeters in 1 centimeter. So, each centimeter is equivalent to 10 millimeters.

So,One centimeter = 10 millimeters.Therefore,the correct option is A.

In summary, the conversion from centimeters to millimeters is achieved by multiplying the value in centimeters by the conversion factor of 10. This results in the final answer of one centimeter being equal to 10 millimeters.

The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle.Always, sometimes, or never

Answers

Answer:

Polygon: A polygon is a simple closed curve entirely made up of line segments.

1. As starting from triangle

Three kind of triangles: Isosceles, Scalene , and equilateral triangle

In none of these  measure of an exterior angle at the vertex of the triangle equals the measure of the adjacent interior angle.

2. Quadrilateral = Parallelogram, Rhombus, Rectangle, Square, Kite, Trpzm

Apart from Rectangle and Square none other quadrilateral have The measure of an exterior angle at the vertex of the quadrilateral equals the measure of the adjacent interior angle.

we can also consider other polygons also like pentagon,hexagon,heptagon.

Decagon and found that it is not always possible that measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle.

So, the correct option is Sometimes.



so an exterior angle at the vertex of a polygon not can being never equal the measure of the adjacent interior angle
