It is the second answer choice
Step-by-step explanation:
- 7x + 3x - 18 = 6(x + 3) === Given
- 10x - 18 = 6(x + 3) === Combine Like Terms === 7x + 3
- 10x - 18 = 6x + 18 === Distributive Property === 6(x + 3)
- 10x - 18 - 6x = 18 === Subtraction Property of Equality === -6x both sides
- 4x - 18 = 18 === Combine Like Terms === 10x - 6x
- 4x = 18 + 18 === Addition Property of Equality === +18 both sides
- 4x = 36 === Combine Like terms === 18 + 18
- x = 36 / 4 === Division Property of Equality === /4 both sides
- x = 9 === combine like terms??
That doesn't use the multiplication property but that's all of the rest of them.
Using proportions, considering the income tax of 10%, you actually earn $1,215 a month.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For people earnings less than $19,000 a year, the income tax is of 10%, hence the amount you actually earn is given by:
A = 0.9 x 1350 = $1,215 a month.

In the left one x equals 12.9 and on the right one x equals 11
The relationship would be that 1/4 ÷ 4 and 1/4 × 1/4 are the same.
This is because, if you were going to work out 1/4 ÷ 4, you would start with writing it as 1/4 ÷ 4/1.
Then, the rule for dividing fractions is you flip the second fraction and change the divide sign to a multiply sign, so that gives you 1/4 × 1/4.
I hope this helps!
