The value of x for the given equation (x + 50)/2 = 13x is 2.

According to the given question.

We have an equation (x + 50)/2 = 13x, which represents when two tutoring services with different rate plans charge the same fees for a session of x hours.

So, we have to solve the given equation (x + 50)/2 = 13x for x.

Therefore,

x + 50 = 2(13x)

⇒ x + 50 = 26x

⇒ 26x - x = 50

⇒ 25x = 50

⇒ x = 50/25

⇒ x = 2

Hence, the value of x for the given equation (x + 50)/2 = 13x is 2.

An anthropologist has determined that a newly discovered human bone is 8000 years old. how much of the original amount of carbon

AlladinOne [14]

The original amount of carbon 14 that is in this bone is 38.29%

The formula that is used to determine the original amount of carbon 14 in the bone is given as:

$y = ae^-^0^.^0^0^0^1^2^t$

The value of t is given as 8000.

What is to be done is to solve the equation using the value of t

$y = ae^-^0^.^0^0^0^1^2^(^8^0^0^0^)$

= ae⁻⁰.⁹⁶

Solve for exp(-0.96)

y = 0.3829a

= 38.29%

Therefore the amount of carbon 14 that is in the bone is 38.29%
