18+2.50=20.50 so tax is 10% so you can put that into a calculator as 20.50*0.10 which equals 2.05 so just add 20.50 and 2.05 which is 22.55 is your final answer
5 square units let me know if it’s correct hun
The formula for the area of a circle is r² x π.
-Since we know the diameter of the circle, we can divide by 2 to find the radius of the circle.
10/2 = 5
-From here, we can substitute our values in. Since we're using 3.14 for pi, we'll substitute that as well.
(5)² x (3.14)
-And finally, we can solve to find the area of the circle.
(25) x (3.14)
(78.5)
Therefore, the answer is 78.5 meters.

90-x*30=80
90-30x=80
90-90-30x=80-90
-30x=-10
Divide by -30 for -30x and -10
-30/-30x=-10/-30
x=1/3
Answer:
11.05
Step-by-step explanation:
2x-5=18
2x+5=23
2x/2=2/23
x=11.05
