Answer:
140
Step-by-step explanation:
If it is an arc of 7pi/3, and the circumference is 6*pi or 6pi, then the arc takes up 7/18 of the circle, and since a circle has 360 degrees, the answr is 7/18 * 360 or 140.
Answer:
c
Step-by-step explanation:
in c, one of the domains has 2 ranges so it is not a function
12 boys, because 4x8=32, and 4x3=12!
The answer is y=-2 and x=4 ,,, tell me if you need the work
13 + x/2 = 3x
=> to solve this first convert 13 and x/2 into like fractions(with same denominators) ...
=> 13 is also 13/1
=> so 13/1 = 13/1 * 2 = 26/2
=> 26/2 + x/2 = 3x => (26+x)/2 = 3x
=> 26 + x = 3x*2
=> 26 = 6x - x
=> 5x = 26
=> x = 26/5
=>x = 5.2
hope it helps !!!!
