$\frac{2.75}{9} =\frac{x}{(2/9)}$

To solve this proportion, cross multiply.

By cross multiplying, you will multiply 2.75 * (2/9) and 9 * x.

0.61 = 9x

Divide both sides by 9.

x = 0.067... which rounds to 0.068, so your answer is:

D) x $\approx$ 0.068

Answer:

The correct answer is 31x + 0.5

Step-by-step explanation:

∵ 13x + 5 + 17x - 4.5 + x

To solve this correctly you must to add the coefficients of the like terms (terms who has same variables or constant terms)

∵ 13x , 17x , x are like terms ⇒ terms with same variable

(same letters and same power)

∵ 5 , 4.5 are like terms ⇒ constant terms (numbers only)

∴ (13x + 17x + x) + (5 - 4.5) = 31x + 0.5

* The error of first answer:

- 18x + 17x - 4.5 + x

- She add 13x + 5 = 18x ⇒ she add unlike terms

* The error of second answer:

- 35x - 4.5 + x

- She add 13x + 5 + 17x = 35x ⇒ she add 2 like terms with 1 unlike term

* The error of third answer:

- 30.5x + x

- She add 13x + 5 + 17x - 4.5 = (13x + 17x) + (5 - 4.5) =

30x + 0.5 ⇒ she add 2 like terms and 2 constant terms

and then add the 2 unlike answers

* The error of fourth answer:

- 31.5x

- She add 13x + 5 + 17x - 4.5 + x = (13x + 17x + x) + (5 - 4.5) =

31x + 0.5 ⇒ she add 3 like terms and 2 constant terms

and then add the 2 unlike answers

George and veronica are both musicians who sell their sogn online during the same year George sold 8x10^5 download of his song a

anygoal [31]

George sold:

$\begin{gathered} 8\times10^5 \\ =800,000 \end{gathered}$

and Veronica sold:

$\begin{gathered} 4\times10^6 \\ =4,000,000 \end{gathered}$

As expanding the scientific notation numbers, we see that

George sold eight hundred thousand

Veronica sold 4 million

How many time is 4 million of 8 hundred thousand?

We simply divide!

$\frac{4,000,000}{800,000}=5$

So,

Veronica's song was downloaded 5 times the numebr of that of George.

B is the right answer.
