Which number is not a solution of $\frac{t}{-9}\ge 3$?

1. $-35$
2. $-30$
3. $-27$
4. $-25$

In this type of inequality, Simply use the property of addition or subtraction of suitable number on both Left Hand Side & Right Hand Sideto maintain the inequality and also the variable & numbers should be at the different sides in the equation.

Here, the inequality is $\frac{t}{-9}\ge 3$

To solve this, simply multiply $-9$to both side of the equation

$\begin{array}{l}\frac{t}{-9}\ge 3\\ \frac{t}{-9}\times -9\ge 3\times -9\\ t\ge -27\end{array}$

a. $-35$:This is not a correct option because the value of solution greater than or equal to $-27$but $-35$is smaller than role="math" localid="1647894324698" $-27$.

b. role="math" localid="1647894290638" $-30$: This is not a correct option because the value of solution greater than or equal to $-27$ but $-30$is smaller than $-27$.

c. $-27$: This is a correct option because the value of solution is greater than or equal to $-27$and here $-27$is equal to $-27$.

d. $-25$: This is a correct option because the value of solution is greater than or equal to $-27$ and here $-25$ greater than $-27$.
