Hi!

So obviously we have to divide each side by -5. It's pretty simple! Let me show you...

-125 ≥ -135
-125/-5 ≥ -135/-5
dividing 2 negative numbers make a positive
25 ≥ 27
Now that the expression has changed, we have to flip the inequality sign.
25 ≤ 27
^the answer

Hope this helps! :)

Find the area of sector AOB. Express your answer in terms of pi and rounded to the nearest tenth.

STatiana [176]

63 $\pi$

The sector is $\frac{70}{360}$ ; there are 360 degrees in a circle.
You use the formula $\pi r^{2}$ .
18cm is the radius, and then you square it to get 324.
Multiply 324 by $\frac{70}{360}$
You get 63 $\pi$
