Divide 3 from both sides to get a=57/3 then a=19
X+17.92+15.33=72.31
-17.92
-15.33
x= 39.06
The amount you started with was $39.06.
Hope this helps ;}
Related angle is 45 degrees, set up a triangle and use exact trig values to solve for x and y, then rationalise the denominators
The answer is B.
....................................
(3/2)x-1<2x+4
3x-2<4x+8
-2<x+8
-10<x
x>-10
3((2/3)x + 1) < 11
(3*2/3)x+1*3<11
2x +3<11
2x<8
x<4
so the compound equality is the set of all numbers which are >-10 or <4, which are D) all real numbers
