Question

Select the action you would use to solve x/4 = 16. Then select the propertys that justifies that action.


1. Property: Multiplication property of equality.

2. Action: Add 4 to both sides

3. Action: Divide both sides by 4.

4. Property: Addition property of equality.

5. Property: Division property of equality.

Answer 1

Answer:

The right options are A and D.

Step-by-step explanation:

1. Option A.

The action is:Add 3 to both sides. This means that we need to do the following operation:

x - 3 = 12

∴ x - 3 + 3 = 12 + 3

∴ x = 15

So, the solution of this problem is x = 15.

2. Option D.

The property is:Addition property of equality. This is the property we are chosen because we need to isolate the variable x. To do that, we need to add a number of each side of the equation to find our goal and this property allows us to get our goal.

Answer 2

The value of x is 64 and the property that justifies that action is  the multiplication property of equality option (1) is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

x/4 = 16

Apply Multiplication property of equality:

Multiply by 4 on both sides:

(x/4)4 = 16×4

x = 64

Thus, the value of x is 64 and the property that justifies that action is  the multiplication property of equality option (1) is correct.
