Question

Substitute the value into the variable, and state (in a complete sentence) whether the resulting number sentence is true or false. If true, find a value that would result in a false number sentence. If false, find a value that would result in a true number sentence.

1. 15 + n = 22. Substitute 7 for n.

1. 39 < 13g. Substitute 3 for g.

1. f43. Substitute 12 for f.

1. 122-98r. Substitute 23 for r.

Answer 1

1.. True. 15+7=22. Eleven plus seven equals twenty-two. let n=6 and it's false

1. False. . 39=13(3) = 39. but 39 is not less than 39. A number is not less than itself. If g=4, then the inequality is true. Thirty nine is less than thirteen times four. 39<52
