Hello, there!
<span>Ten times a number is sixteen more than twice the number. Find the number.
Answer: 2

First, let's write the equation.
Ten times a number -- 10x
16 more -- 10x - 16
Twice the number -- 2x
10x - 16 = 2x or 10x = 2x + 16
Let's use the first one: 10x - 16 = 2x
First, let's isolate the x to one side.
10x - 16 = 2x
-10x -10x
-16 = -8x
Now, let's multiply each side by -1 to make them positive
-16 = -8x
*-1 *-1
16 = 8x
Finally, let's divide each side by 8
16 = 8x
---- ----
8 8
Our answer is 2 = x
This means that the number is 2.
I hope I helped!
Let me know if you need anything else!

To do the mean of the numbers, you have to add them all together and divide them by the number of numbers:
65 + 125 + 90 + 100 = 380
There are 4 numbers, so you have to do
380 ÷ 4 = 95
The mean of those numbers is 95
Answer:
False
Step-by-step explanation:
The short reason the statement is false is, "it depends on what you mean by <em>direction angle</em>".
The long reason the statement is false is that "direction angle" sometimes refers to a navigation direction that is specified in terms of compass directions. For example, you might have N20°E, or S80°E. The angle measure in such directions is 0 to 90°. It does not take on a negative value when the direction is expressed in the standard form, an angle east or west from north or south.
An arbitrary vector is an expression that has a magnitude and direction. Such a quantity can have either or both values be positive or negative and of <em>any magnitude</em>. There is no reason for direction to be restricted to values in the range ±90°.
Answer:
s = 23
Step-by-step explanation:
Given VW ≅ VY then VX is a perpendicular bisector of WY then Δ WXY is isosceles with XY = WX , that is
4s = s + 69 ( subtract s from both sides )
3s = 69 ( divide both sides by 3 )
s = 23
