Answer:
x<3/2
Step-by-step explanation:
12x+7<-11
12x<-11-7
12x<-18
x<-3/2
24 + 3r = 100
Subtract 24 from both sides.
24 - 24 + 3r = 100 - 24
Divide
3r = 76
3r/3 = 76/3
r = 25.3
Rounded to 25.

-4 I'm not 100% but I think this is the answer
Given:
To find:
The obtuse angle between the given pair of straight lines.
Solution:
The slope intercept form of a line is
...(i)
where, m is slope and b is y-intercept.
The given equations are
On comparing these equations with (i), we get
Angle between two lines whose slopes are is
Putting and , we get
Now,
and
and
and
, so it is an obtuse angle and , so it is an acute angle.
Therefore, the obtuse angle between the given pair of straight lines is 120°.
