Answer:

6a + (6 x 3) = 60

6a + 18 = 60

Step-by-step explanation:

You have 6 students who are assigned an unknown amount of problems. We can write it as 6x. Then each is given 3 more problems, so now we have 6x + (6 x 3). We also know that in all they have 60 problems.

Therefore, the equation is:

6x + 18 = 60

Then just solve

6x + 18 = 60

- 18 -18

6x = 42

x = 7

Eddi Din [679]

Answer:

$\huge\boxed{A_R=18\pi\ cm^2}$

Step-by-step explanation:

$\dfrac{80^o}{360^o}=\dfrac{8}{36}=\dfrac{2}{9}$

The shaded region is 2/9 of whole circle.

Calculate the area of a circle:

$A=\pi r^2$

$r$ - radius

Substitute $r=9cm$

$A_O=\pi\cdot9^2=81\pi(cm^2)$

Calculate the area of the shaded regions:

$A_R=\dfrac{2}{9}A_O\\\\A_R=\dfrac{2}{9}\cdot81\pi=2\cdot9\pi=18\pi(cm^2)$
