Answer:
270
Step-by-step explanation:
use lising method start with the larger number
54:54,108,162 216,270
15: instead of listing all 18 multiples, divide 15 into the multiples of 54 it only goes evenly into 270.
Or divide both denominators into your fir answer and see the smallest bith can go into evenly.
Multiply first equation by -5 and 2nd by 2, add them
15x+20y=-100
<u>2x-20y=32 +</u>
17x+0y=-68
17x=-68
divide both sides by 17
x=-4
the x value is -4
Answer:
The sum of the first 8 terms in the series is 65535.
Step-by-step explanation:
We have,
The common ratio in a geometric series, r = 4
First term of GP is, a = 3
It is required to find the sum of the first 8 terms in the series. The sum of first n terms of a GP is given by :
Here, n = 8
So, the sum of the first 8 terms in the series is 65535.
So there’s a flat fee of 2 and that’s like a standalone thing so our equation would be
2 + 1.50m
Assuming m = 9, it would be 2 + 13.50
And the two answers are-
A) $15.50
B) 2 + 1.50m
There you go. Let me know if you have questions
