Answer:
30/45 or 2/3
Step-by-step explanation:
If you factor out a 10 from the numerator and a 9 from the denominator, you should get the following:
Numerator = 10 (a + b)
Denominator = 9 (x - y)
Since we know that (a + b) = 3 and (x - y) = 5, we can rewrite it as:
Numerator = 10(3)
Denominator = 9(5)
Therefore, the answer is 30/45, or 2/3.

Answer:
(a)
(b)
(c) Jim initially had 48; Kirk initially had 12
Step-by-step explanation:
Given
Solving (a): An equation for the amount they originally had.
From the question, we understand that j is 4 times as many as k.
Mathematically, this is:
Solving (b): Equation after Kirk wins
Initially Kirk had k.
To get the new expression, we add 18 to k.
This gives: 18 + k
In the same vein, Jim's number of chirps will reduce by 18.
Initially, Jim had j chirps (or 4k chirps)
To get the new expression, we subtract 18 from j.
This gives: j - 18
So, the equation is:
Solving (c): Number of chirps they started with.
In (b), we have:
Substitute 4k for j

Divide both sides by 3
Substitute 12 for k in
Answer:
C. 69.08 inches
Step-by-step explanation:
Find the distance the wheels will travel by finding the circumference of the wheel.
Use the circumference formula, C = 2r
Plug in 11 as r in the equation, and 3.14 as pi, then solve:
C = 2r
C = (2)(3.14)(11)
C = 69.08
So, the correct answer is C. 69.08 inches
