Answer:

4x+6y

Step-by-step explanation:

I hope you understand it now. The multiplication is only for the 2y. 2x+x+x=4x

2y × 3= 6y

So it will be 4x+6y.

It's easy isn't it?

Okay, here we have this:

Considering the provided information, we are going to identify wich equation applies, so we obtain the following:

x+19=2x

Where x represents the uknown number. Then finally we obtain that the correct equation is the third one.

Now, let's find the missing number solving the equation:

\begin{gathered} x+19=2x \\ 19=2x-x \\ 19=x \end{gathered}

Finally we obtain that the number is equal to 19.

The amount of carbon-14 in an object is given by y = ae– 0.00012t where a is the initial amount of carbon and t is the age in ye
Reptile [31]

Answer:

The approximate age of the bone is approximately 11552 years.

Step-by-step explanation:

The current proportion of carbon-14 with respect to its original amount is defined by following formula:

\frac{y}{a} = e^{-0.00012\cdot t} (1)

Where:

y - Current amount of carbon-14, no unit.

a - Initial amount of carbon-14, no unit.

t - Time, in years.

If we know that \frac{y}{a} = 0.25, then the approximate age of the bone is:

t = -8333.333\cdot \ln \frac{y}{a}

t\approx 11552.453\,yr

The approximate age of the bone is approximately 11552 years.

I WILL MARK YOU BRAINLIEST!!
Butoxors [25]

Answer:

Yes

Step-by-step explanation:

There is a proportional relationship between x and y it's 5.

Think about it when x is 1 y is 5

When x is 2 y is 10

When x is 5 y is 25

When x is 7 y is 35

To get this for this question all you have to do is multiply x by 5 to get y.

That's how you know it's proportional.

Hope this helps!!!
