[(0.24*5)+ (0.66*5)] == 4.50
0.24x5 = 1.20
0.66x5 = 3.30
+ ____
4.50
27.00÷4.5 = 0.166666667
Ignore above
your equation is 2(cosx)^2-3cosx+1=0
use quadratic formula to get results
you will end up with
cosx=1 or cosx=1/2
so, x=0 or x=pi/3
4y:5y would be the simplest form
If you switch it around, it'll be: 1,707 - 264
Subtract:
1,707 - 264 = 1443
Answer = 1,443
