») If 5y = 25, which property of equality was used to keep the equation 5y - 7 = 25 - 7 equal?

») Convince Me!

What other properties of equality could you apply to

keep the equation 5y = 25 equal? Give an example of

each.

a. Subtraction property

b. Addition property and Multiplication property

Step-by-step explanation:

Given

Solving (a): Which property is applied to

The property applied is the subtraction property of inequality, and it states that:

If

Then

So, in this case:

Solving (b): Other properties

1. The additive property of equality

If

Then

So, the expression can be written as:

When 12 is subtracted from both sides, the equation returns to the original

i.e.

2. The multiplication property of equality

If

Then

So, the expression can be written as:

When both sides are divided by 2, the equation returns to the original

i.e.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
