Full solution

Q. Is

r = 7

a solution to the inequality below?

\newline

r < 9

\newline

Choices:

\newline

(A) yes

\newline

(B) no

Substitute $r$ with $7$ : To determine if $r = 7$ is a solution to the inequality r < 9, we need to substitute $r$ with $7$ and check if the inequality holds true. $\newline$ Substitute $r$ with $7$ : 7 < 9 $\newline$ Check if the inequality is true: Since $7$ is less than $7$ $0$ , the inequality is true.
