The answer is the polygon have 24 sides.
Solution is shown step by step: Let c be the 15 degrees.
1. C = 360 divided by n
2. 15 = 360 divided by n
3. then transpose n to the other side
15n = 360
4. divide both sides by 15
n = 360 divided by 15
5. n = 24
Answer:
11(t+r)+35
Step-by-step explanation:
they make 11 dollars an hour so you have to multiply 11 by t hour an r hours. then only one of them worked overtime so you add 35.
Answer:
20
Step-by-step explanation:
Let's start by rewriting the second equation in terms of "x":

Subtract y from both sides:

Now, substitute "5-y" for "x" in the first equation:

Note that:


Cancel out like terms:

Subtract 25 from both sides:

Divide both sides by -10

Now, substitute this value back into either of the equations to solve for x.

Add 15/2 to both sides:

Now, find the difference:
