Answers

Answer 1

Answer:

Answer:

$19.85

Step-by-step explanation:

$20-0.15=x$

$Switch\: sides$

$x=20-0.15$

$\mathrm{Subtract\:the\:numbers:}\:20-0.15=19.85$

A farmer in china discovers a mammal hide that contains 25% of its original amount of c-14

Answers

Plato answer is 13863

You have left a LOT out of your question. However I'll attempt to post an answer.

The half-life of carbon 14 is 5,700 years.

If there is 25% of the original carbon 14 remaining that means the time it has undergone has been 2 half lives.

2 half-lives of carbon14 = 2 * 5,700 = 11,400 years.

Therefore , the solution of the given problem of equation comes out to be the system of equations' answers are (-1, -5) and (1, -5).

What is an equation?

The foundation of a regression model based on linearity is the equation y=mx+b. The inclination is B, and the y-intercept is m. Even though y but also y are separate components, the above line is frequently referred as the "mathematical issues with two variables". Two factors make up bivariate linear equations. There are no simple answers for the applications of linear functions. Y=mx+b .

Here,

We can change the second equation into the first equation to find the solution to the system of equations, which results in:

=> x² + (x²-6) = -4

By condensing and rearrangeing, we obtain:

=> 2x² = 2

=> x² = 1

Consequently, x can either be 1 or -1.

We can determine the appropriate values of y by substituting these values of x into either of the two equations:

When x Equals 1:

=> y = x² - 6 = 1 - 6 = -5

When x Equals -1:

=> y = x² - 6 = 1 - 6 = -5
