Basically, you are looking for the ARC SINE of .994 which is
83.72 Degrees
You could also use an online calculator:

2+x=2x-15
>> 2+15=2x-x
>> 17 = x
So the answer is <u>17</u>
If you would like to know in which step did the student first make an error and what is the correct step, you can calculate this using the following steps:
3(2x - 4) = 8 + 2x + 6
6x - 12 = 8 + 2x + 6
6x - 12 = 14 + 2x ... Step 2
6x - 2x = 14 + 12
4x = 26
x = 26/4 = 13/2
The correct result would be Step 2; <span>6x - 12 = 14 + 2x.</span>
9.4061,
9.07,
9.007,
9.4
Because ones are equal for all numbers, we are going to begin to compare from the second digits (tenths).
Greater :
9.4061 and 9.4.
Greatest is this group is 9.4061, then will go 9.4.
Smaller :
9.07 and 9.007
Greatest in this group is 9.07, and then will go 9.007.
So, from greatest to smallest : 9.4061 , 9.4 , 9.07 , 9.007.
From least to greatest :
9.007, 9.07, 9.4, 9.4061.
4 , divide the x by the y to find a constant
