Answer:
Step-by-step explanation:
Given
For 5 people

Where
--- The first term
--- The last term
So:
Answer:
n=-6
Step-by-step explanation:
2n + 10 = -2
2n=-12
n=-6

If not I'm sorry.
Answer:
2 hours
Step-by-step explanation:
First we need to know the distance Liam travelled using the bike.
If his speed was 8 mph and he travelled 3 hours, the distance travelled by bike is:
d = 8 * 3 = 24 miles
The total distance is 30 miles, so the remaining is:
30 - 24 = 6 miles
He travelled 6 miles with the speed of 3 mph, so the time walking is:
time = 6 / 3 = 2 hours
A tangent forms a right angle with the centre of circle at the point it touches the circumference. i.e. OAB = 90 degrees
If AOB = 55 degrees, then ABO = 90 - 55 = 35 degrees
Answer:
nope it is equal to 84/100 though
Step-by-step explanation:
cross multiply
21 x
-------- -----------
25 100
21*100= 2100
2100/25= 84
x=84
