Answer:
Multiplying a number by n is equivalent to dividing it by 1/n.
Step-by-step explanation:
We generalise for any whole number n.
Answer:
cos(C)
Step-by-step explanation:
Recall that the sine ratio is opposite over hypotenuse.

Also the cosine ratio is adjacent over hypotenuse.

The tangent ratio does not come close because it doesn't involve the Hypotenuse.

Answer:
the number is 3
Step-by-step explanation:
Perhaps you'd like to find the number.
If n represents the number, we can write the relationship as ...
3n -1 = n +5
Adding 1-n to both sides gives ...
2n = 6
n = 3 . . . . divide by 2
The number is 3.

The product of the number and 3 is 9. One less is 8. That is 5 more than the number itself: 8 = 3 + 5.
Answer:
The value of
.
Step-by-step explanation:
Given:

We need to solve this equation.
Solution:
First combining equation having same denominators we get;

Now denominators are common so we will solve the numerators we get;

Now by cross multiplication we get;

Now Applying distributive property we get;

Now Combining the like terms we get;

Hence on solving we get the value of
.
