Question

CAN SOMEONE HELP ME SOLVE THIS EQUATION GIVEN FROM A PREVIOUS POST?? {MEDAL!!!}

(n+3)(x-1)=216

Answer 1

solve for?

Answer 2

n or x ?

Answer 3

n

Answer 4

(n+3)=216/(x-1)
n = 216/(x-1) - 3

Answer 5

Then what can I do?

Answer 6

\[n = \frac{216-3(x-1)}{x-1}\]

Answer 7

\[n=\frac{216-3x+3}{x-1}=\frac{219-3x}{x-1}\]

Answer 8

\[n=\frac{3(73-x)}{x-1}\]

Answer 9

That's about it..

Answer 10

So what does n equal to?

Answer 11

Depends on value of x, if x = 0, then n=-219, or if x =1, n is undefined. etc.

Answer 12

Well I had this one question that I needed help on. Someone did, but then they gave me an equation which I had no idea on how to solve it. But can you please help me and explain all this material to me?

Answer 13

Ella spent her whole allowance of $2.00, plus the 16¢ she had left over from last week, on
bubble gum. If the pieces of gum had been a penny cheaper, she would have received three
more pieces than she did. How many pieces did she actually buy?

Answer 14

Use a little dab of algebra for this bubble gum problem.
Given cost is 216 cents for total gum purchased
Let x = the number of pieces of gum at original price.
then 216/x = price of gum at original price.
Now for the if portion.
if price per gum is 1 cent less then would of cost (216/x)-1 per piece (give)
the if or new quantity purchased would be x + 3 (given) From this we can state (mathematically):
(x+) [(216/x)-1)] = 216 now solve listed are some intermediate steps
\[x ^{2}+3x-648 =0\]
(x+27)(x-24) = 0
x=24 getting the gum a 9 cents a piece.
if x = 27, if gum sold at 8 cents a piece. the Lesson being don't spend your entire allowance on bubble gum.
