Question

What is the solution to 3 x + 2.4 greater-than-or-equal-to 3.0?
x greater-than-or-equal-to 0.2
x greater-than-or-equal-to 0.6
x greater-than-or-equal-to 1.8
x greater-than-or-equal-to 2.5

Answer 1

To solve this, you need to isolate/get the variable "x" by itself in the inequality:

3x + 2.4 ≥ 3.0       First subtract 2.4 on both sides

3x + 2.4 - 2.4 ≥ 3.0 - 2.4

3x ≥ 0.6      Now divide 3 on both sides to get "x" by itself

$\frac{3x}{3} \geq \frac{0.6}{3}$

x ≥ 0.2       Your answer is the 1st option

Answer 2

Answer:

A

Step-by-step explanation:

The inequality at hand is:

3x + 2.4 ≥ 3.0

We solve for x like a regular equation:

3x + 2.4 ≥ 3.0

3x ≥ 0.6

x ≥ 0.2

Now, we see that all the solutions to the given inequality must be greater than or equal to 0.2.

Thus, the answer is A.
