Answer:
y = 6/5
Step-by-step explanation:
3x - 5y = -3
Let x =1
3(1) - 5y = -3
3-5y = -3
Subtract 3 from each side
3-3-5y = -3-3
-5y = -6
Divide each side by -5
-5y/-5 = -6/-5
y = 6/5
Answer:
Step-by-step explanation:
No. Each side must be less than the sum of the remaining two sides.

Step-by-step explanation:
5/9 = 0.5555555
The smallest sequence of repeating digits in the decimal equivalent of 5/9
0.5
0.5 + 0.05
0.5 + 0.05 + 0.005
0.5 + 0.05 + 0.005 + 0.0005
Hence, the number of digit in the smallest sequence of repeating decimal is 1
5/9 = 0.5....
Let's denote Cindy's age which is unknown with X
We know that Cindy's age is 3 times her age 6 years ago.
6 years ago Cindy's age was the present age (X) - 6 : X-6
The fact that the present age is 3 times her age 6 year ago can be written as:
3*(X-6)
So, finally:
X=3*(X-6)
