All you have to remember is this. Reverse the operation. For example on this problem there is a -2 right? So reverse the operation and (REMEMBER:Always do what you did on one side to the other side) then you would have +2 on both sides. You do the same for variables and all of the numbers and result with 8x=2, so divide by 8 and get x=1/4

Step-by-step explanation:
Yes the answer is correct
Answer:
Step-by-step explanation:
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
