Answer: Choice A
Filled in circle at 5; shading to the right
================================================
Explanation:
Think of it as x+5 = 10. You'd solve for x by subtracting 5 from both sides. This is to undo the addition operation.
So you'll do the same for the inequality to get . The graph of which consists of a closed filled in circle at 5 on the number line. Then we shade to the right. This visually describes any x value that is 5 or larger.
So that's why the answer is choice A
The answer is: 4.5 cups.
The explanation is shown below:
1. You need 3 cups of milk to make 30 biscuits.
2. Therefore, to solve the exercise you only need to multiply 45 biscuits by 3 cups and divide this by 30 biscuits.
3. Let's call the cups you will need to make 45 biscuits . Then, you have:
4. Therefore, you will need 4.5 cups to make 45 biscuits.
