82 / n - 26 is the correct expression (that's the 4th choice).
Choice 2 is also correct. Also the 5th is correct.
82 / 2 - 26
= 41 - 26 = 15
So the last choice is also correct.
Step-by-step explanation:
The given equation is :
2x = 10
We need to find the value of x.
This equation has one solution as it is a linear equation having one variable i.e. x.
Dividing both sides by 2,
x = 5
So, the value of x is equal to 5.
Put x = 5. So,
2(5) = 10
10 = 10
Hence, this is the required solution.
Answer:
the paper need to be 16 inches
We know that
180 degrees is equal to pi radians
so
for 30 degrees
180°--------> pi radians
30°--------> x
x=30*pi/180------> x=pi/6 radians
for 60 degrees
180°--------> pi radians
60°--------> x
x=60*pi/180------> x=pi/3 radians
for 90 degrees
180°--------> pi radians
90°--------> x
x=90*pi/180------> x=pi/2 radians
the answer is the option c
pi/6,pi/3,pi/2
