 3(r-6) +2 = 4(r+2) -21
3r - 6r +2 = 4r +8 -21
     -3r +2 = 4r -13
            2 = 7r -13
          15 = 7r
             r = \frac{15}{2}
             r = 7.5

A board game contains a cube withone of the letters A, G, E, I, K, and W on each of its faces. With each roll, what is the proba

The probability that a vowel will land face up on the cube would be 1/2. This is because there are six total letters; three vowels and three consonants, so there is a 3/6 chance of it being a vowel and you simplify it down to 1/2. I hope this helped :)
