$90 because 200-10=180 and divide 180 by 2 which is 90.
1/6 because you are breaking something into 6 and you got to share think of it like that so you get a smaller piece than you cutting it into 1/5...... so the answer is 1/6
Log16 4 = 2
log base 16 then the number four then set that equal to 2
8x - 32 = 6 - 9x
17x = 38
x = 38/17
444 divided by 3 equals 148
