Step-by-step explanation:

First, divide both sides of the equation by -6.

-6(r-98)÷6=78÷6

This gives us r-98=-13

Then, add 98 to both sides.

r-98+98=-13+98

The answer is r=85

Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approxim

Firlakuza [10]

Answer:

Option C $=8.4672\times10^{13}$

Step-by-step explanation:

Given : Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approximately 5,880,000,000,000 miles.

Suppose a star is 14.4 light years from earth.

To find : How many miles away a star is from earth?

Solution :

In 1 light-year the distance a light can travel is = 5,880,000,000,000 miles.

or = $5.88\times 10^{12}$ miles

In 14.4 lights year the distance is $=14.4\times (5.88\times10^{12})$

$=84.672\times10^{12}$

or $=8.4672\times10^{13}$

Therefore, Option C is correct - $=8.4672\times10^{13}$

the following data values represent a population. what is the variance of the values? 17, 5, 11, 1, 11

Vladimir [108]

Variance = summation of (x - mean)^2 all divided by the number of dataset.
mean = (17 + 5 + 11 + 1 + 11)/5 = 9

Variance = [(17 - 9)^2 + (5 - 9)^2 + (11 - 9)^2 + (1 - 9)^2 + (11 - 9)^2]/5 = (8^2 + (-4)^2 + 2^2 + (-8)^2 + 2^2}/5 = (64 + 16 + 4 + 64 + 4)/5 = 152/5 = 30.4

4. When Megan solved this system using the elimination method, she added the equations together and got the equation 4y = 16. Th

Ede4ka [16]

Hi there!

So, our two equations are:
2x + 3y = 20 and
-2x + y = 4

We can see that the x's will cancel out because they're the same number, opposite signs. Then we're left with 4y = 24.

Divide 24 by 4, which is 6.

y = 6, then we plug that in to the first equation for y:
2x + 3(6) = 20
2x + 18 = 20
2x = 2
x = 1

So, she made her first mistake when adding the equations, adding 20 and 4, she somehow got 16.

The solution to the system is (1,6).

I hope I helped!
