Answer:

Step-by-step explanation:

3(n+4)=1/2(6n+4)

We simplify the equation to the form, which is simple to understand

3(n+4)=1/2(6n+4)

Simplifying:

3*(n+4)=0.5*(6n+4)

Reorder the terms in parentheses

+(+3n+12)=0.5*(6n+4)

Remove unnecessary parentheses

+3n+12=0.5+*(+6n+4+)

Reorder the terms in parentheses

+3n+12=+(+3n+2)

Remove unnecessary parentheses

+3n+12=+3n+2

We move all terms containing n to the left and all other terms to the right.

+3n-3n=+2-12

We simplify left and right side of the equation.

n=-10

0=-10

The left and right sides are not equal, therefore there is no solution. This equation is invalid.

85

Step-by-step explanation:

Pythagorean Triples obeys the Pythagoras Theorem.

We want to find is the value of x if (13, 84, x) is a Pythagorean triple.

We apply the Pythagoras Theorem to obtain:

{x}^{2}= {84}^{2}  +  {13}^{2}

We simplify to get:

{x}^{2}= 7056+ 169

{x}^{2}  = 7225

Take positive square root;

x =  \sqrt{7225}  = 85

Please I could use some help!

Answer:

the year is 2016

Step-by-step explanation:

The computation is shown below:

Given that

The population in 2009 is 45.1 million

And it would be increased 2.3% each year

So,

In the year 2010 it is = 45.1 million × (1 + 0.023) = $46.14 million

In the year 2011, it is = $46.14 million × (1 + 0.023) =$47.20 million

In the year 2012, it is = $47.20 million × (1 + 0.023) = $48.29 million

In the year 2013, it is = $48.29 million × (1 + 0.023) = $49.40 million

In the year 2014, it is = $49.40 million × (1 + 0.023) = $50.54 million

In the year 2015, it is = $50.54 million × (1 + 0.023) = $51.70 million

In the year 2016, it is = $51.70 million × (1 + 0.023) = $52.89 million

Hence, the year is 2016
