All answers should be the same, but it's different between degree and radian mode. (Deg and rad)
...What trigonometric function do you want us to use?
Subtract both sides by 27: -n>=-6
Divide by negative 1, and flip the sign. (Always do that when dividing by a negative number.)
n<=6
249.6/320=78%
Find the greatest common factor of the numerator and denominator, and divide the two by the GCF.
9, since 9 is the highest power in the polynomial.
Just type sin(4) on any calculator to find out.
Start off by distributing the 3(2x+4): 6x+12+8=50.
6x+20=50, subtract both sides by 20: 6x=30.
You know what to do from here.
Here you go, pretty easy to understand, I think.
Go here and type in the system of equations.
