Answer 1

Given ↓

• The inequality 2x+5≥15

To Find ↓

• The solution to the inequality

Calculations ↓

First, subtract 5 on both sides

2x≥15-5

2x≥10

Now divide by 2 on both sides

x≥5

The correct option is Option A

Answer 2

Option A

Explanation:

Step 1: Solve the equation

`2x + 5 \geq 15`

`2x + 5 - 5 \geq 15 - 5`

`2x \geq 10`

`2x / 2 \geq 10/2`

`x \geq 5`

Step 2: What model represents the equation

Seems like option A represents the best because it showcases 2 x's and 5 +1's on the left side which is then greater or equal to the right side with 10 +1's.

Answer: Option A
