Question

Determine if each is a true or false number sentence.

1. 5n >25 if n=5

1. 22 - h 100 if h=10

1. c + 9 = 15 if c=6.5

Answer 1

false. 25 is not greater than 25. 25=25, but a number is not greater than itself.

false 22-10 = 12 but does not equal 100

false 6.5 + 9 = 15.5 which does not equal 15, but it's close
