Employees salary [$}: 30,000, 30,000, 35,000, 35,000, 40,000, 40,000.

CEO Salary: $70,000.

The correct answer is this: BOTH JAN AND MARCY ARE CORRECT.

Jan says the employee average salary is $35,000. This is correct as shown below:

Average employee salary = 30,000 + 30,000 + 35,000 +35,000 + 40,000 + 40,000 / 6 = 210 / 6 = $35,000.

Marcy says the average salary of all company members is $40,000. This is also true as shown below.

Average salary of all company members = 30,000 + 30,000 +35,000 + 35,000 + 40,000 + 40,000 + 70,000 / 7 = 280 / 7 = $40,000.

Solve the system equation

<h2>Answer:</h2>

We will use substitution to solve this system for x.

$x - 2y = 27\\y = 5x\\\\x - 2(5x) = 27\\\\x - 10x = 27\\\\-9x = 27\\\\x = -3$

Now that we know what x is, we can determine y by pluging in -3 for x in one of the original equations. I will use the first one.

$-3 - 2y = 27\\\\-2y = 30\\\\y = -15\\$

We now have our solution.

D. $(-3, -15)$

We can check our answer by pluging the solution into one of the original equations to see if both sides equal each other. I will use the first equation.

$-3 - 2(-15) = 27\\\\-3 + 30 = 27\\\\27 = 27$

Since the equation checks out, our solution is correct.

A penny fell off the top of the building and hit the sidewalk below 3.1 seconds later how many meters did the penny fall to the

Sedbober [7]

To solve this we are going to use the free distance fallen formula: $d=0.5gt^2$
where
$d$ is the distance
$g$ is the gravity of Earth $9.8m/s^2$
$t$ is the time in seconds

We know from our problem that the penny fell off the top of the building and hit the sidewalk below 3.1 seconds later, so $t=3.1$ . Lets replace the value in our formula:
$d=0.5gt^2$
$d=0.5(9.8)(3.1)^2$
$d=47.089$ meters

We can conclude that the penny fell a distance of 47.098 meters

Which is the equation of a line that has a slope of 1/2 and passes through point 0 , -2

S_A_V [24]

The general equation of a line is y = mx + b
m is given as 1/2, so we have:
$y=\frac{1}{2}x+b$
Plugging in the given values of x and y, we get:
-2 = 0 + b
Therefore b = -2, and the answer is:
$y=\frac{1}{2}x-2$
