Answer:
$110
Step-by-step explanation:
So first you have to do 15*4. We get the 4 from the admission fees and the 15 from the number of dances they attend. From this answer we can see the total of money they will be paying for admission for the 15 dances.
15*4=$60
However, our answer isn't just $50 as we are also told membership costs $50. So no we add $50 to $60, which gives us an answer of $110, which is the amount the member will pay if they attend 15 dances during the school year.
Answer: 122 1/2 minutes
Step-by-step explanation:
I got this answer by first subtracting 5.25-3.50=1.75 and that was how many minutes it took per mile then I multiplied 1.75x70=122.50 to get my answer.
Answer:
2j-42
Explanation:
The phrase is “42 less than twice Janelle’s age”. Basically, this can be separated into “42 less than” and “twice Janelle’s age”. “Twice Janelle’s age” infers that Janelle’s age is doubled; This can be achieved by 2j because it multiplies Janelle’s age by 2(Times 2 is doubling, times 3 is tripling, and times 4 is quadrupling). The second part is “42 less than” meaning something, in this case Janelle’s age, is subtracted by 42 because less than means negative/minus; This is written as “-42”. So, when we put “42 less than Janelle’s age” together, it becomes -42+2j, which ordered correctly becomes as 2j-42.
Answer:
G 15.99h > 188.55 + 9.75h
Step-by-step explanation:
I have a solution here for the same problem but a different given:
<span>(2x-82)/(x^2+2x-48) dx
</span>
In which this solution will help you answer the problem by yourself:
(2x - 82) /(x² + 2x - 48)
<span>first, factor the denominator completely: </span>
<span>(x² + 2x - 48) = </span>
<span>(x² + 8x - 6x - 48) = </span>
<span>x(x + 8) - 6(x + 8) = </span>
<span>(x - 6)(x + 8) </span>
<span>so the function becomes: </span>
<span>(2x - 82) /[(x - 6)(x + 8)] </span>
<span>let's decompose this into partial fractions: </span>
<span>(2x - 82) /[(x - 6)(x + 8)] = A/(x - 6) + B/(x + 8) </span>
<span>(letting [(x - 6)(x + 8)] be the common denominator at the right side too) </span>
<span>(2x - 82) /[(x - 6)(x + 8)] = [A(x + 8) + B(x - 6)] /[(x - 6)(x + 8)] </span>
<span>(equating numerators) </span>
<span>2x - 82 = Ax + 8A + Bx - 6B </span>
<span>2x - 82 = (A + B)x + (8A - 6B) </span>
<span>yielding the system: </span>
<span>A + B = 2 </span>
<span>8A - 6B = - 82 </span>
<span>A = 2 - B </span>
<span>4A - 3B = - 41 </span>
<span>A = 2 - B </span>
<span>4(2 - B) - 3B = - 41 </span>
<span>A = 2 - B </span>
<span>8 - 4B - 3B = - 41 </span>
<span>A = 2 - B </span>
<span>- 7B = - 41 - 8 </span>
<span>A = 2 - B </span>
<span>7B = 49 </span>
<span>A = 2 - 7 = - 5 </span>
<span>B = 49/7 = 7 </span>
<span>hence: </span>
<span>(2x - 82) /[(x - 6)(x + 8)] = A/(x - 6) + B/(x + 8) = - 5/(x - 6) + 7/(x + 8) </span>
<span>thus the answer is: </span>
<span>(2x - 82) /(x² + 2x - 48) = [- 5 /(x - 6)] + [7 /(x + 8)] </span>
