The correct answer would be 72*10^11 or 72e+11 or 720000000000
I think you are asking if -8x ≥ 40, find x. What we do here is we divide negative 8 by both sides. This gives us x ≥ 5. BUT, we have to be careful!!!! When we divide an inequality on both sides by a negative number, we have to switch the sign. Thus, our answer is x ≤ 5.
Step-by-step explanation:
72/64=x/8
=> x = (72×8)/64
=> x = 9.
hope this helps you.
26.315789, you should use a caculator
Answer:
22 sides
Step-by-step explanation:
The expression to find an interior angle of a polygon is:
The expression to find an exterior angle of a polygon is:
Please note that "n" represents the number of sides the polygon has.
We can use these two expressions to set up an equation.
Multiply both sides by "n":
Now, distribute:
Divide both sides by 10:
Add 36 to both sides:
Divide both sides by 18:
The polygon has 22 sides
