Answer:
- Mean score=120
Step-by-step explanation:
- Areas of a triangle add upto 180degrees (63+78+x=180) 141+x= (x=180-141) x=39
- Areas on a straight line add upto 180degrees
180-78=102
180-63=117
180-39=141
- 102+117+141=360
- Mean=360/3 =120
Answer:

Step-by-step explanation:

Isolate x on one side of the equation.
Find the value of x.
First, multiply -1 from both sides.
(-3/4x)(-1)<12(-1)
Solve.
12(-1)=-12
3/4x<-12
Next, multiply 4 from both sides.
4*3/4x<4(-12)
Solve.
Multiply the numbers from left to right.
4(-12)=-48
3x<-48
Then, divide by 3 from both sides.
3x/3<-48/3
Solve.
Divide the numbers from left to right.
-48/3=-16
X<-16

The correct answer is x<-16.
