Answer:
c. 17
Explanation:
So the equation is 3g = 51.
What we are given is {15, 16, 17}
Let's plug in each of these into the equation for g.
3(15) = 51
45 = 51
45 does not equal 51.
3(16) = 51
48 = 51
48 does not equal 51
3(17) = 51
51 = 51
51 does equal to 51.
So 17 is your answer, because if you plug it into the equation, you get an equivalent answer of 51.
