1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 6/3
You would place a #line going from negatives on left to positive on right then place a point at positive 5 and go back 5, 3 times
You want to find R. From angle R, you know the side lengths for opposite and hypotenuse. According to SohCahToa, that is sine. Sin (x) = Opposite / Hypotenuse = 2.5 / 5 = 0.5
Sine(x)=.5. To get x by itself divide both by the inverse of sine.
Equation: 0.5x + 8.3
Plug in 12 for x and solve

5 less than 3.1 times a number n:
3.1n-5
Four more than the quotient of 12 and a number n:
n/12+4
Hope this helps you!
