HELP PLEASE FOR 35 POINTS!!!! Solve the rational equation 3 divided by x equals quantity 4 times x plus 3 divided by x squared,
denis23 [38]

Answer:

x=-3

Step-by-step explanation:

So, we are given:

\frac{3}{x}=\frac{4x+3}{x^2}

First, we should immediately rule out 0 as an answer. This is because the if x=0, the equation would be undefined.

x\neq 0

Now, cross multiply.

3(x^2)=x(4x+3)

3x^2=4x^2+3x

Divide everything by x (and we can do this safely because we already know x cannot be equal to zero).

3x=4x+3

-x=3

x=-3

We didn't run into any possibilities for extraneous solutions.

Diane has $1.40 in dimes and nickels. She has a total of 16 coins. How many of each kind does she have?
Kazeer [188]

9514 1404 393

Answer:

  • 4 nickels
  • 12 dimes

Step-by-step explanation:

Let d represent the number of dimes. Then 16-d is the number of nickels, and the total value is ...

  0.10d +0.05(16 -d) = 1.40

  0.05d + 0.80 = 1.40 . . . . . . . eliminate parentheses

  0.05d = 0.60 . . . . . . . . subtract 0.80

  d = 12 . . . . . . . .dimes

  (16 -d) = 4 . . . . nickels

Diane has 12 dimes and 4 nickels.
