Answer:
Step-by-step explanation:
We remove the bracket and rearrange the numbers to add them. Only similar variables can be added together.
Answer:
270kilometers
Step-by-step explanation:
To find the distance, all you have to do is the speed · time
In these types of distance time and word problems, you multiply the other factors, 90 and 3, The time(T) · The speed(S)
So. 90(S) · 3(T) = 270(D)
It would be nice to know some options, but here's Morris's speed.
Since Morris is traveling at three feet per second, we want to change it to per hour.
3 * 3600 = 10800 feet per hour
And we would want to convert that to miles per hour.
10800/5280 is about 2, more specifically 2.05 ish.
So Morris is traveling 2 mph less then 50, or about 48 mph.
The format is y = mx + b
where y would be your C
x would be your M
m would be the price per mile (2.20)
and b would be your initial fee (2.75)
put this together in that format and we get
C = 2.20M + 2.75

Answer:
a9 = -8 +9(9 -1)
Step-by-step explanation:
The given sequence has a common difference of 1-(-8) = 10-1 = 9, and a first term of -8. The formula for the n-th term of such an arithmetic sequence is ...
an = a1 +d(n -1) . . . . . first term a1, common difference d
For the parameter of this sequence, a1=-8 and d=9, the n-th term is ...
an = -8 +9(n -1) . . . . formula for the n-th term
__
Then the formula for the 9th term is ...
a9 = -8 +9(9 -1)
