The expression with the same values of (1/x – y) in x and y will be 10 / 7.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression x-y equals 0.7.
x - y = 0.7 …1
If x and y have certain values.
Then the expression with the same values of (1/x – y) in x and y will be
Take the reciprocal of equation 1, then we have
1 / (x – y) = 1 / 0.7
1 / (x – y) = 10 / 7.

Step-by-step explanation:
Since no other info is given, you would use a protractor, centered at O. Read off the degree measure, to the nearest degree (a high quality protractor may have divisions to a quarter of a degree). Arc AC has that many degrees.
If the angle is ABC, where B is also on the circle, this is called an inscribed angle, with vertex (its”point”) at B. Now, arc AC will have exactly twice the degree measure of angle ABC. That is a theorem in geometry textbooks, which has been known for about 2500 years!
Answer:
0.84
Step-by-step explanation:
Divide 63 by 75 and you get 0.84 (84%).
Answer:
x = 5/32 = 0.156
Step-by-step explanation:
The boat is 428.9 feet from the lighthouse.
To solve this, draw a right triangle. You will see that you have an angle of 25 degrees with an opposite side of 200 and the adjacent side is x.
We can write and solve the following tangent equation:
tan(25) = 200 / x
x = 200 / tan(25)
x 428.9
