Solve for x<br> -6x > 78

Anestetic [448]

Hi!

To find x, you'll need to divide by -6 on both sides of the equation. When -6x s divided, you're left w/ x. When 78 is divided by -6, you'll get -13.

So your answer is x<-13. You'll need to switch the sign because 13 is a negative so the greater than sign is turned into a less than sign. S your answer is D.

I hope this helps!

The area of a circle is 16pi cm2. What is the circle's circumstance?

gavmur [86]

I think you mean circumference...Area is $A= \pi r^{2}$ . We have the area so we need to use it to solve for the radius which we will then use in the circumference formula. $16 \pi = \pi r^{2}$ . Divide both sides by pi to get $\frac{16 \pi }{ \pi } = r^{2}$ . Of course the simplification of the left side gives us $16= r^{2}$ and r = 4. Now fill that in to the circumference formula, which is $C=2 \pi r$ , to get C $C=2 \pi (4)$ which is a circumference of $8 \pi$
