1. if we add something in x then it will also add up in value of y
2. x by 5 times then y value increases by 3*5 = 15 times
3. if x is added with 5 then y value increases by 8.
<h3>What is Algebra?</h3>
Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.
As, per the first part
y=x
So, if we add something in x then it will also add up in value of x.
In second part,
y=3x
If x by 5 times then y value increases by 3*5 = 15 times
In third part, if x is added with 5 then y value increases by 8.

Answer:
107
Step-by-step explanation:
you will add 60 + 32 +15 = 107 that is how i got the answer
The equation r = u/st is equivalent to u = rst .
True
To show this number using scientific notation, you will look at where the decimal point is and imagine that in the original number. Then count the number of place values to the right of this. That will be the exponent that belongs with the 10 because that is how many place values (groups of 10s) the number has past the decimal point.
The answer is 3.31 x 10^26 light years. ^ means to the power of.
Answer:
1.) 
≈ 3.652
2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.
Step-by-step explanation:
I think we may have the same class so hopefully this helps:
1.) 
--> law of cosines formula.
--> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.
--> in between steps.
--> more simplifying.
--> answer
2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.
Good luck! :)
