Answer:
I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.
For example, if you have the following inequation:
x-2> 1
x>3
Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U (3, inf) instead of 'x>3 or x<-3' which can be confusing.
So angle DBC is equal to 180° - 28° which is 152°

Answer:
ans:- 14
Step-by-step explanation:
let length = x
so, width= 2x -1
perimeter= 2(l +b)
82 = 2(x+ 2x-1)
41 = 3x - 1
3x = 42
x = 14
Answer:
Step-by-step explanation:
9x + 8 = 7.5x + 17
1.5x = 9
x = 6 hours
