X would equal 4
set AB=AC
18=3x+6
minus 6 on both sides
12=3x
divide both sides by 3
x=4
W = words per minute = 80
t = time in minutes = 30
The total number of words per 30 minutes is w*t = 80*30 = 2400 words
1 1/4 + 1/2 + 3/4 =
5/4 + 1/2 + 3/4 =
5/4 + 2/4 + 3/4 =
10/4 = 2 1/2 (or 2.5) oz's <
Because thats not how its pronounced anymore.
Happy studying ^_^
