1. 4(x � 1) + 6 = 3x + 1 � 2x (solve for x)
4x-4+6=x+1
4x-x=1+4-6
3x=-1
x=-1/3 ans.
2. (x � 2)/4 � 1/5 = (7x + 1)/20
(x-2)/4-(7x+1)/20=1/5
[5(x-2)-7x-1]/20=1/5
(5x-10-7x-1)/20=1/5
5(-2x-11)=20
-10x-55=20
-10x=20+55
-10x=75
x=75/-10
x=-7.5 ans.
3.Find the area of a triangle whose base is 1.3 feet and whose height is 1.5 feet.
a=bh/2
a=1.3*1.5/2
a=1.95/2
a=.975 ans.
