Answer:
= 39 - 10n
Step-by-step explanation:
There is a common difference between consecutive terms , that is
19 - 29 = 9 - 19 = - 10
This indicates the sequence is arithmetic with nth term ( expicit formula )
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 29 and d = - 10 , then
= 29 - 10(n - 1) = 29 - 10n + 10 = 39 - 10n
Answer:
Speed = 800 km/hr
Step-by-step explanation:
Distance = 2000 km
time = 2.5 hours
Speed = distance / time
= 2000/2.5
= 800 km/hr
The 8 and 4 are like terms and can be added and since it is all addition we wind up with:
9t +12
144 ounces! There are 8 ounces in 1 cup. 8x18= 144!! :D
Answer:
Step-by-step explanation:
21% more then 5/11...
5/11 + 21% of 5/11 = 5/11 + 0.21(5/11) = 5/11 + (21/100 * 5/11) =
5/11 + 21/220 = 11/20 <===
