Answer:
t+3r
Step-by-step explanation:
This is a one step solution
All you do is add like terms
In this case the only like terms are the varibles r
2r+(t+r)
so if you add all of the rs together there would be 3rs
So the rest of the problem would continue as normal while bringing the 3r to the end
t+3r
Answer:
Step-by-step explanation:
Sum of interior angle of any polygon =(n-2) × 180°where n represents the number of sides in any polygon.
Or 1260 =(n-2)x180
Dividing both sides by 180:
7=n-2
Adding both sides by 2 we have :
n=9.
Hence a nanogon will have the sum of interior angles as 1260°.
Answer: x = 1500/ n
Step-by-step explanation:

Answer:
5.1 days
Step-by-step explanation:
Cross Multiply
Divide both sides of the equation by 3.4
Answer:
No answer as written. 16 if we add an equals sign.
Step-by-step explanation:
As written, there is no "=" sign in either expression. That means they are only expressions, not equations. x can be anything. 10, 12345, 0.00000343345567788, etc. There is nothing that restricts the value of x.
If we set the two expressions equal to each other, we can calculate a value of x:
(2x + 30) = (5x - 18)
3x = 48
x = 16
