yes
Step-by-step explanation:
just plug in
2+3 is equal to 5 so that works
4(2)+13(3) is greater than 20 so that also works
Answer:

Step-by-step explanation:
Six more than the quotient of four and a number x:

Answer:
Step-by-step explanation:
Given is a picture of circle with angle
BOC =7x-11
Also angle of arc BC = angle BOC = 3x+53
Since both are the same equate the two

Now substitute this x value in any one of 3x+53 or 7x-11
Angle COB = angle BOC = 3x+53
= 48+53 = 101 degrees
-------------------------
To find length of arc
Central angle = 101
Hence arc lengh =
I hope this is right 5+4 and 3+6
