Awhole number is 6 more than 2 times another number. the sum of the two numbers is less than 50. this can be written in an inequality as x + 2x + 6 < 50, where x represents the smaller number.
from the set {13, 14, 15, 16, 17}, the values of x for which the inequality holds true are

a: {13, 14}

b: {13, 14, 15}

c: {15, 16, 17}

d: {16, 17}
