The equation to find the circumference of a circle is ...
c = π × d
All we need to do to find circumference is to <em><u>multiply</u></em> the diameter (16km) by pi (π)
c = π × 16
c = 50.27
Answer:
A
Step-by-step explanation:
x=5 is the opposite of -5 so it can be eliminated
y=x-5 is not giving you the x intercept and same with y=-x+5
By definition, an astronomical unit in miles is given by:
As it is in exponential notation, then we must rewrite.
Therefore, an astronomical unit is:
93 million miles
Answer:
93 million miles
Answer:
4x + 8y = 17
Solve for y.
You want to get y on one side of the equal sign by itself so... you subtract 4x from both sides to get:
8y = -4x + 17
Then you divide both sides by 8 to get:
y= -4x/8 +17/8
Then simplify the fractions to get:
y = -2x/4 + 17/8
Step-by-step explanation:
From the second:
2x-y=4
x=(4+y)/2 and applying this to first:
4+y+3y=12
4y+4=12
4y=8
y=2 and since x=(4+y)/2, x=3 so
x+y=2+3=5
