Answer:
(61. 8181..., ~)
Step-by-step explanation:
-11/5x<-136
x>680/11
x>61. 8181...
4-7x= 39
Subtract 4 from both sides
-7x= 35
Divide both sides by -7
x= -5
The value of x+1= (-5)+1= -4.
Answer:
355
Step-by-step explanation:
3
-5
=3*5³-5*2²
3*5³-5*2²=3*125-5*4
3*125-5*4=375-20
375-20=355
Answer:
8
Step-by-step explanation:

9-1=8
Answer:
a = 93°, b = 120°, c = 150°
Step-by-step explanation:
b + 36 = 78 × 2 => b + 36 = 156 => b = 120°
87 × 2 - b = the minor arc between a and 78
=> 174 - 120 = 54
54 + b + 36 + c = 360
=> 54 + 120 + 36 + c = 360
=> c = 150°
(c + 36) ÷ 2 = a
=> (150 + 36) ÷ 2 = a
=> a = 93°
