And finally we have:
5.56666666667 as a fraction equals 556666666667/100000000000
I can help!! But could you tell me what the equations are?
Answer:
B. A cow of 5 years is predicted to produce 5.5 more gallons per week.
Step-by-step explanation:
Let
, where
is the age of the dairy cow, measured in years, and
is the predicted milk production, measured in gallons per week.
Besides, we consider
and
, such that
, we define the difference between predicted milk productions (
) below:
(1)
If we know that
and
, then the difference between predicted milk productions is:

That is, a cow of 5 years is predicted to produce 5.5 more gallons per week than a cow of 10 years. Hence, the right answer is B.
Answer:
9r+13
Step-by-step explanation:
To solve this question, all we need to do is simplify the equation.
The equation is 8r+7+4+r. To simplify, we need to add like terms.
8r+r+7+4=9r+13
9r+13 is the equivalent equation to 8r+7+4+r.
Hope this helps!
