Question

Which inequality is true if n = 81? F 3n < 84 G n − 29 < 53 H 2n < 162 J n + 5 < 76

Answer 1

G n − 29 < 53

Explanation:

If n = 81 ;

Put n = 81 into each and see if it holds true:

F 3n < 84

3(81) < 84

243 < 84 - - - - untrue

G n − 29 < 53

81 - 29 < 53

52 < 53 - - - - - True

H 2n < 162

2(81) < 162

162 < 162 - - - - untrue

J n + 5 < 76

81 + 5 < 76

86 < 76 - - - - - untrue

Only true statement :

G n − 29 < 53
