Select the property of equality used to arrive at the conclusion. If x = 4, then 5x = 20 the addition property of equality the m
shtirl [24]

Answer:

The Division Property of Equality

Step-by-step explanation:

<u>The Addition Property of Equality:</u> When you add something to one side of the equation, you must add the same thing to the other side.

<u>The Subtraction Property of Equality:</u> When you subtract something from one side of the equation, you must subtract the same thing from the other side.

<u>The Multiplication Property of Equality:</u> When you multiply something to one side of the equation, you must multiply the same thing to the other side.

<u>The Division Property of Equality:</u> When you divide something from one side of the equation, you must divide the same thing from the other side.

In this case, you have to divide both sides of the equation by 5 to get x = 4. That means that the division property of equality was used.

I hope this helps! Have a great day!

What 2 numbers have a difference in 54
nata0808 [166]

Hey! :)

Let us make these number be x and y.

x + y = 54

x - y = 26

Now, add these equations to get the following:

2x = 54 + 26 = 80

2x = 80

x = 80/2 = 40

Now, x + y = 54 meaning 40 + y = 54.

Therefore y = 54 - 40 = 14.

Have a great rest of your day :)
