The average atomic mass is 6.92X

How do we compute the average atomic mass?

In a bid to calculate the average atomic mass, we multiply the fraction of each isotope by the mass number , then add them together.

This is more like weighted average, as shown below:

average atomic mass=(mass number of first isotope*fraction)+(mass number of second isotope*fraction)

average atomic mass=(6X*7.59%)+(7X*92.41%)

average atomic mass= 6.92X

Y = –3x 6 y = 9 what is the solution to the system of equations? (–21, 9) (9, –21) (–1, 9) (9, –1)

Romashka [77]

we have

<u>The system of equations</u>

$y=-3x+6$ -------> equation $1$

$y=9$ -------> equation $2$

Substitute equation $2$ in equation $1$

$9=-3x+6$

subtract $6$ both sides

$9-6=-3x+6-6$

$3=-3x$

Divide by $-3$ both sides

$x=-1$

the solution is the point $(-1,9)$

therefore

the answer is

the solution to the system of equations is the point $(-1,9)$

Find the distance between (6, -7), (3, -5) round your answer to the nearest tenth

saw5 [17]

Answer:

d ≈ 3.6 units

Step-by-step explanation:

calculate the distance d using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (6, - 7 ) and (x₂, y₂ ) = (3, - 5 )

d = $\sqrt{(3-6)^2+(-5-(-7))^2}$

= $\sqrt{(-3)^2+(-5+7)^2}$

= $\sqrt{9+2^2}$

= $\sqrt{9+4}$

= $\sqrt{13}$

≈ 3.6 ( to the nearest tenth )
