Answer:
A
Step-by-step explanation:
Hello,
The answer is x= y-13 / 2 ( everything after the x= is a fraction)
How to solve;
Start by subtracting 13 from both sides of y=2x+13, we do this to get the x on 1 side
So now we have y-13=2x
Next divide both sides by 2, we do this to get x by it self.
y-13/2=x
Now we flip the problem and there you have it!
Edit: The x does not have a Pos or neg value, The only way to know what x is, is to solve for x.
Answer:
$200
Step-by-step explanation:
Represent the regular price of the chair by c.
Then 0.25c =$50, and c = $200.
The regular price, c, was $200.
Answer:
cos(L) = 12/13
Step-by-step explanation:
The hypotenuse of the triangle is LM = 13. The side adjacent to angle L is LN = 12. (It has L in the name.) The cosine is the ratio of the adjacent side to the hypotenuse:
Cos = Adjacent/Hypotenuse
cos(L) = LN/LM
cos(L) = 12/13
