A constant is a value in a formula that does not change its value.
For example, in the formula:
PV = nRT
The constant is R.
It means that regardless of the value of the other variables, R will always remain the same.
R: universal constant of gases.

Answer:
4
Step-by-step explanation:
if the required number is 'x', then the sum of 2 times the number and 10 is 2x+10; the difference of the number and 1 is x-1. Using these two equation it is possible to make up the common one:
2x+10=6(x-1);
4x=16;
x=4.
Answer:
A
Step-by-step explanation:
I believe that it is C
Explanation:
Answer:
1) EA= 50 (because is a vertical angle with CB and vertical angles are congruent)
3) DEB = 210 ( to find AB subtract EA from 180, so 180-50 = 130. Then add together arcs DE, EA and AB to find the total measurement of DEB)
5) AB = 130 (I explain how to find it in question #3)
6) CDA = 180 ( To find CDA just add the measurements of CD, DE and EA together)
(sorry don't know the rest, hope this helps)
