6 times the difference of a number and 4 equals 7
Nonamiya [84]
6( x - 4) = 7
6 x - 24 = 7
6 x = 7 + 24
6 x = 31
x = 31/6 

6 ( 31/6 - 4) = 7 
186/6 - 24 = 7
186/6 = 144/6 = 7

42/6 = 7 
7 = 7

A wheel has a diameter of 21 inches. <br><br> Approximately how far does it travel in 3 revolutions?
RideAnS [48]
So each 1 revolution it travels the distance around the rim of the wheele aka circumference
circumference=pi times diameter
diameter=21
circunference=pi times 21 or 21pi
so distance=number of revolutions times circunference
number of revolutions=3
subsitute

distance=3 times 21pi
distance=63pi

answer is 63pi
or aprox pi to 3.14 and do 63 times 3.14=197.82
aprox 197.82 inches
