Question

check for reasonableness in 20–27, name three solutions of each

1. ( x > 10.5 )
2. ( r < -19 )
3. ( y geq - )

Explanation:

For problem 20: \( x > 10.5 \)

Step1: Understand the inequality

We need to find numbers greater than 10.5.

Step2: Choose three solutions

We can pick any real numbers greater than 10.5. For example, 11, 12, and 13 (we could also use decimals like 10.6, 10.7, 10.8).

Step1: Understand the inequality

We need to find numbers less than -19.

Step2: Choose three solutions

We can pick any real numbers less than -19. For example, -20, -21, -22 (we could also use numbers like -19.5, -19.6, -19.7).

Answer:

Three solutions for \( x > 10.5 \) are 11, 12, 13 (or other valid numbers like 10.6, 10.7, 10.8).

For problem 21: \( r < -19 \)
