Answer:
55 pirates for 5 ships, 121 pirates for 11 ships
Step-by-step explanation:
for every 2 ships he needs 22 pirates, divide both by 2 and we see that for every ship he needs 11 pirates, also can write as 2x= 22 and divide both sides by 2, x=11 now that we know for every ship he needs 11 pirates we just multiply 11 times the amount of ships or 11x=y, 11 times 5 is 55 and 11 times 11 is 121
Answer:
The function that represents the average cost in dollars of saleable software CD is given as follows;
f(x) = 500,020/x + 0.10
Step-by-step explanation:
The given parameters are;
The cost of manufacture of each software CD = $0.10
The development cost to produce the CD = $500,000
The number of CDs that are not sold = The first 200 CDs
The total cost of production. 'C', of the the CD is given as follows;
C = $500,000 + $0.10×200 = $500,020
The function, 'f' for the average cost in dollars of a saleable software CD where 'x' is the number of saleable software CDs is given as follows;
f(x) = (C + 0.10·x)/x = C/x + 0.10
∴ f(x) = 500,020/x + 0.10.
Let the numbers = x, x+1, x+2
It is given that, x + x+1 + x+2 = 84
3x + 3 = 84
3x = 84 - 3
3x = 81
x = 81/3
x = 27
Largest number, x+2 = 27+2 = 29
In short, Your Answer would be 29
Hope this helps!

Answer: Choice D. </h3>
Morgan forgot to distribute the negative sign to two of the terms in the second expression.
=============================================================
Explanation:
Focus on the numerators.
We have (3t^2-4t+1) as the first numerator and we subtract off (t^2+2t+2) as the second numerator.
Morgan needs to simplify (3t^2-4t+1)-(t^2+2t+2) for the numerator.
Mistakenly, she had these steps
(3t^2-4t+1)-(t^2+2t+2)
3t^2-4t+1-t^2+2t+2 .... her mistake made here
(3t^2-t^2)+(-4t+2t)+(1+2)
2t^2-2t+3
All of this applies to the numerator. The denominator stays at t+3 the entire time. So effectively we can ignore it on a temporary basis.
Here's what Morgan should have for her steps when simplifying the numerator.
(3t^2-4t+1)-(t^2+2t+2)
3t^2-4t+1-t^2-2t-2 ..... distribute the negative
(3t^2-t^2)+(-4t-2t)+(1-2)
2t^2-6t-1
Note in the second step, the negative outside flips the sign of each term in the second parenthesis.
Therefore,

which means 
Side notes:
- The fractions can only be subtracted since the denominators are the same.
- We have
to avoid a division by zero error. - Rational expressions are a fraction, or ratio, of two polynomials.
