Answer:

(3/2, 6)

Step-by-step explanation:

y = 4x

8x + y = 18

this says y is 4x so you can replace y with 4x

8x + 4x = 18

12x = 18

/12 /12

x = 3/2

now sub x into y = 4(3/2)

y = 12/2

y = 6

<h3>Answer: 14400</h3>

Chances are your teacher doesn't want you to enter any commas. You won't type in the dollar sign either.

============================================================

Explanation:

Nice work on selecting the correct equation to set up.

We'll cross multiply to help solve for x.

The idea of cross multiplication is that $\frac{A}{B} = \frac{C}{D}$ turns into $A*D = B*C$

So,

$\frac{5040}{280000} = \frac{x}{800000}\\\\5040*800000 = 280,000*x\\\\4,032,000,000 = 280,000x\\\\280000x = 4,032,000,000\\\\x = \frac{4,032,000,000}{280,000}\\\\x = 14,400\\\\$

That means the person would pay $14,400 on a property worth $800,000.

How is factoring related to using the distributive property

xeze [42]

In the above statement, the number 3 is a common factor between the two terms in the statement, 3x and 3y. We can divide 3 into both numbers evenly. This is also called “factoring<span> out” 3. Finding the common factor allows us to apply the </span>Distributive Property<span> to the statement.
Hope this helps</span>
