So these are our two equations: 
Before we can use elimination, subtract y on both sides of the first equation: 
Now we are able to use elimination. To eliminate the y variable, add the two equations together to get 
. From here we can solve for x.
For this, just divide both sides by 3 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:
<u>In short, x = 3 and y = 6.</u>
Answer:

Step-by-step explanation:
<u><em>The correct question is</em></u>
A circle has a circumference of 8. It has an arc of length 32/5 . What is the central angle of the arc,in the degrees?
we know that
The circumference of the circle subtend a central angle of 360 degrees
so
uing a proportion
Find out the central angle for an arc of length 32/5
Answer:
$47.50
Step-by-step explanation:
You just take $380 and divide it by 8 hours to get the amount of money per hour, which is $47.50 .
Answer:
7
Step-by-step explanation:
arithmetic sequence: aₙ = a₁ + (n-1)d
a₈ = (-5) + (8-1)d = 37
7d = 42
d = 6
a₃ = -5 + (3-1) x 6 = 7
