Solve this equation:

Answer: correct choice is D
5 + 4 = 9
117/ 9 = 13
13 x 4 = 52 cats
Answer:
x = 22
Step-by-step explanation:
The sum of the angles round a point is 360°
Sum the given angles and equate to 360
x + 6x + 40 + 3x + 100 = 360
10x + 140 = 360 ( subtract 140 from both sides )
10x = 220 ( divide both sides by 10 )
x = 22
12. x= 4
13. x= 4
14. x= -1
