r(x) / s(x)
= r/s (x)
= (3x - 1)/ (2x + 1)
so if r/s (6)
= [3(6) - 1] / [(2(6) + 1]
Answer is the first option
3(6) - 1
--------------
2(6) + 1
Answer:
Step-by-step explanation:
(-3 feet)/(4 weeks) = -¾ foot per week
A number is divisible by 9<span> if the sum of its digits is </span><span>divisible by 9
here the sum 39 not divisible by 9 </span>
TRUE. I don't know for other languages, but in English you surely can do that.

=

Multiply both sides by 12, so that we get rid of the fraction in x.
12 · (x+3)/12 = 2/7 · 12
Simplify.
x + 3 = 24/7
Then, subtract 3 from both sides, so that "x" gets isolated.
x = 24/7 - 3
Turn "3" into an improper fraction so that we could find the value of x easier.
3 = 21/3
So :
x = 24/7 - 21/7
Simplify.
x = 3/7
