1 is D, an angle bisector only cuts the original angle in half.
2 is
9x - 18 = 3x
6x - 18 = 0
6x = 18
x = 3
3 is 9(3) - 18 = 27 - 18 = 9
Replace the informations you don't know with letters.
x = number of bags
y = number of sandwiches
7x + 3y = 22
3x + y = 8
Then solve the equations.
First, isolate the y in the second one like this :
y = 8 - 3x
then replace the y in the first equation with its worth from the second equation :
7x + 3(8 - 3x) = 22
solve for x, then replace the value in the equations to get the value of y
I can tell you how to solve this problem.
You can find the areas using both the values as the radiuses (find the are of a circle).
Subtract the smaller area from the larger area and there is your answer.
Hope this helped.
Good Luck!

The required function of the situation is f(x) = 2670x.
Step-by-step explanation:
Given,
Population is = 3000
Evert year it is decreased by 11%.
To find the function of the given situation.
Formula
If the original population is a and is decreased by b% the population after 1 year will be a×
After x year the population will be = a××x =
Now,
Let after x years the population will be,
f(x) = 3000x×
= 2670x
Hence,
The required function of the situation is f(x) = 2670x.
