Answer:
s = 35pi units
We can either leave it with pi in the answer or approximate 
s= 109.9557429 units
Step-by-step explanation:
Arc length is found by
s = r * theta where r is the radius and theta is given in radians
Changing the angle from 150 degrees to radians by multiplying by pi/180
150 *pi/180 = 5/6 pi
Now we can use the formula
s = 42 * 5/6 pi
s = 35pi
We can either leave it with pi in the answer or approximate 
s= 109.9557429 units
 
        
             
        
        
        
J/-2 + 7 = -12 multiply both sides with 2 
-j + 14 = -24 move -14 to the other side and change sign
-j= -24 - 14
-j = -38 and if you divide -38 with -1 you get + 38
j=38

Exp:
18(.25) = 4.5
To convert % to decimal, always move the decimal 2 places to the left.
examples:
25% = 0.25
100% = 1.00
