Question

Which of the following equations demonstrate the multiplication property of equality for the equation x = 2? Check all that apply.
1. x(3) = 2(4)
2. x(5) = 10
3. x(1.5) = 2(2)
4. x(0.5) = 2(0.5)
5. x(12) = 12

Answer 1

X(5)=10 and x(0.5)=2(0.5) are the correct answers.

Answer 2

Answer:

2. x(5) = 10

4. x(0.5) = 2(0.5)

Step-by-step explanation:

Given: x = 2

We need to check all that apply.

1. x (3) = 2(4)

Replace x by 2, we et

2(3) = 2(4)

6 = 8, which is not true.

2. x(5) = 10

Replace x by 2, we get

2(5) = 10

10 = 10

Which is true.

3. x(1.5) = 2(2)

Replace x by 2, we get

2(1.5) = 2(2)

3 = 4, which is not true.

4. x(0.5) = 2(0.5)

Replace x by 2, we get

2(0.5) = 2(0.5)

1 = 1, which is true.

5. x(12) = 12

Replace x by 2, we get

2(12) = 12

24 = 12 which is not true.

Therefore, the following equations demonstrate the multiplication property.

2. x(5) = 10

4. x(0.5) = 2(0.5)
