Answer:
m = -11/6
Step-by-step explanation:
5m -2(m + 2) = -(3m +15)
5m - 2m - 4 = -3m - 15
3m + 3m = -15 + 4
6m = -11
m = -11/6
Answer:
(Area of circle a)/5
Step-by-step explanation:
(Area of circle b) = (1/5)* (Area of circle a)
What is the area of circle a? There is not enough given information
Speed= distance /time
distnace=170 miles
t=2 hours + 45 minutes *(1 hora / 60 minutes=2 hours + 0.75 hours=2.75 hours.
Speed=170 mile / 2.75 hours=61.818...miles/hour≈61.8 miles/hour.
Solution: 61.8 miles/hour.
Answer:
12.496
Step-by-step explanation:
Here, to calculate the sum of the first five terms of the series, we use the formula for the sum of terms in a geometric series.
Mathematically, that would be;
Sn = a(1-r^n)/1-r
where Sn = ?
a = 10
r = 1/5 = 0.2
n = 5
Substituting these values into the equation above, we have;
Sn = 10(1-(0.2)^5)/1-0.2
Sn = 10(0.99968)/0.8
Sn = 12.496
