Question

Which of the following is a true equation? 16 + 4 - 1 = 19 - 1 16 + 4 - 1 = 20 16 + 4 - 1 = 20 - 1 16 + 4 - 1 < 20

Answer 1

Answer:

16 + 4 - 1 < 20

Step-by-step explanation:

16 + 4 - 1 = 19

It cannot be the first equation because 16+4-1 does not equal 19-1. 19 ≠ 18

It cannot be the second or third equation because 19 ≠ 20.

This leaves the last equation where 19 is less than 20. 19 < 20
