Answer:
Step-by-step explanation:
You;ll run into this formula a lot. Make sure you study it carefully.
A = 25
a = 5
d = 13
Find n
25 = 5 + 13*(n- 1)
20 = 13(n - 1)
This isn't going to work out. 20/13 does not give a whole number which it should.
Answer:
x=-8
All you need to do is solve for x. The image shows all the work.
To answer we let x be the amount of money that Sam invested during the first year.
Below are the expressions translated from the given word forms for the amount invested.
Sam:
2nd year : amount = 5x/2 - 2000
3rd year : amount = x/5 + 1000
The sum of money invested by Sam is:
x + (5x/2 - 2000) + (x/5 + 1000)
Similarly, we derive the expressions that we use for the amount that Sally invested.
Sally
1st year : amount = 3x/2 - 1000
2nd year : amount = 2x - 1500
3rd year : amount = x/4 + 1400
The total amount that Sally invested is,
total = (3x/2 - 1000) + (2x - 1500) + (x/4 + 1400)
Equating the two equations:
(x) + (5x/2 - 2000) + (x/5 + 1000) = (3x/2 - 1000) + (2x - 1500) + (x/4 + 1400)
Solving for x,
x = 2000
For Sally's investment in the third year:
amount = x/4 + 1400 = (2000/4 + 1400) = 1900
ANSWERS:
Sam's first year = $2000
Sally's third year = $1900
Answer:
C.
Step-by-step explanation:
A. Is false because citizens do not lose their citizenship if they fail to pay taxes.
B. Is false because not every tax paying citizen receives government assistance gets benifits like food stamps.
D. Is false because taxes don't go directly back to the people as cash payouts.
Answer:
60 km
Step-by-step explanation:
The closure speed of the trains is 30+30 = 60 km/h. Since their initial distance apart is 60 km, it will take 1 hour for them to collide.
The bird flies for 1 hour at 60 km/hour, so flies a total distance of 60 km before being crushed in the collision.
