Answer:
n = 10
Step-by-step explanation:
move all terms to the left:
-2-(-(n-8))=0
calculate terms in parentheses: -(-(n-8)), so:
-(n-8)
get rid of parentheses
-n+8
add all the numbers together, and all the variables
-1n+8
go back to the equation:
-(-1n+8)
get rid of parentheses
1n-8-2=0
add all the numbers together, and all the variables
n-10=0
move all terms containing n to the left, all other terms to the right
n=10
Answer:
2:00 PM
Step-by-step explanation:
I figured out that the car is going 40 mph seeing as how it went 20 miles in 30 minutes.
I used this and found out how many hours it would take to get to 200 miles at this rate:
200/40 = 5
I divided 40 by 200 as 200 is the end goal and the car is going 40 mph.
The 5 is 5 hours, so I added 9 and 5 to get 14 which is 2:00 PM
Hope this helps!! :)
A= pi x radius ^2
A= 3.14 x 5^2
A= 3.14 x 25
A= 3.15 x 25
A= 78.5
60 min = 1 hour
30 times 2 = 60
7.7 times 2 = 15.4
the avg speed is 15.4 km an hour
please mark brainliest :)
