A. It is moved up 3 units.
Answer: The wingspan is 36 m.
Using a proportion to solve this, we write the scale factor as a ratio first: 19/38, since 19 is the size of the model's length and 38 is the real length. For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:
19/38 = 18/x
Cross multiply:
19*x = 38*18
19x = 684
Answer:
x -2 = 3x +2
Step-by-step explanation:
For the purpose, we use math symbols to express the relation described by the English.
<h3>Translation</h3>
When x represents "a number," we have ...
- two less than a number: x -2
- the product of 3 and the number: 3x
- 2 more than the product: 3x +2
- is the same as: =
Then the English description can be translated to ...
x -2 = 3x +2
__
<em>Additional comment</em>
Adding -2-x to both sides gives ...
-4 = 2x
-2 = x . . . . . divide by 2
The number is -2.
Shidddd lil buddy, try the 3rd one
Answer:
x ≈ 4
Step-by-step explanation:
We use tan∅ to solve this:
tan30° = x/7
7(tan30°) = x
x = 4.04145
Remember that tangent is opposite over adjacent.
