Answer:
20078/243
Step-by-step explanation:
sn = a1-a1r^n/1-r
sn = a1 * 1-r^n/1-r
s7 = 6 * 1 - (-5/3)^7/1-(-5/3)
s7 = 6 * 10039/729
s7 = 6 * 10039/243*3
s7 = 2 * 10039/243
s7 = 20078/243
A repeating decimal is when the number repeat or go on forever and do not change
a terminating decimal is one that has an end to it's numbers
example of repeating: .303030303030303.....
example of terminating: .2427
Z = y + 10
I’m not sure if this is the equation you are looking for, but saying that “Z” is equal to “y + 10” is like saying that “Z” is greater than “y” by ten.
I hope this helped! ☻
Answer:
Let’s find out...
Step-by-step explanation:
21 x 13 = 273
(13 x 20) + (13 x 1) =
260 + 13 = 273
So this one matches
(21 x 10) + 213 =
210 + 213 = 423
Does not match
(30 x 13) - (9 x 13) =
390 - 117 = 273
This one matches
(20 x 10) + (1 x 3) =
200 + 3 = 203
Does not match
