27= 3x3x3
54 = 3x3x3x2
so 27/54 = 3x3x3 /<span>3x3x3x2 by simplifying = 1/2</span>
Answer:5.4×105+2.3×104.
Step-by-step explanation:
use cross products
(3r+6) *2 = 9*(2r-4)
6r+12 = 18r-36 distribute
12 = 12 r -36 subtract 6r from each side
48 = 12r add 36 to each side
4=r divide by 12
The rule is that: You are adding 5 each time
5(100) + 4 = 504
Your answer should be 504
hope this helps
