Answer:First three terms: 11,20,29 .
Step-by-step explanation:
Write a systems of equations. tn=a+(n−1)d. sn=n2 (2a+(n−1)d). So,. 110=11+(n−1)d 726=n2(22+(n−1)d).
I hope this is right
$100 to start
-$50 for the original charge
= $50 remaining
$50/.05 = 1000 flyers.
6/y + 1/4 = 5/(4y)
(6*4)/(4*y) + (1*y)/(4*y) = 5/(4y)
24/(4y) + y/(4y) = 5/(4y)
4y≠0 <-->y≠0
24+y=5
y = 5-24
y = -19
Answer:
x = 2
y = -5
Step-by-step explanation:
2x - y = 9
y = x - 7
2x - y = 9
2x - (x - 7) = 9
2x - x + 7 = 9
x + 7 = 9
x = 2
y = x - 7
y = 2 - 7
y = -5
It went wrong in the 2nd step. It doesn't equal -3 it equals positive 3
