191+9 = 200

Romashka [77]

Answer:

\large \boxed{ \boxed{ \tt{g(4) =  -  \frac{16}{3}  \longrightarrow \:  \: Improper \:  \:  Fraction \:  \:  }}} \\  \large \boxed{ \boxed{ \tt{g(4) =  - 5 \frac{1}{3}  \longrightarrow \:  \: Mixed \:  \:  Fraction \:  \:  }}}

Step-by-step explanation:

We are given the function below:

\large{g(x) =  \frac{4x}{3x - 15} }

To find g(4), we simply substitute x = 4 in the equation.

\large{g(4) =  \frac{4(4)}{3(4) - 15} }

Then evaluate the value and simplify in the simplest form.

\large{g(4) =  \frac{16}{12 - 15} } \\  \large{g(4) =  \frac{16}{ - 3} } \\  \large{g(4) =  -  \frac{16}{3} }

Therefore, the value of g(4) is - 16/3

<u>\large{g(4) =  - 5 \frac{1}{3} }</u>

What must be added to each term of the ratio 2:5 so that it maay be equal to 5:6
Kaylis [27]

9514 1404 393

Answer:

  13

Step-by-step explanation:

Let n represent that number.

  (2 +n)/(5 +n) = 5/6 . . . . . . . . n is added to numerator and denominator

  6(2 +n) = 5(5 +n) . . . . . . . . . multiply by 5(5+n)

  12 +6n = 25 +5n . . . . . . . . . eliminate parentheses

  n = 13 . . . . . . . . . . . subtract 5n+12

Adding 13 to each term will give 5/6.

__

<em>Check</em>

  (2 +13)/(5 +13) = 15/18 = (3·5)/(3·6) = 5/6

_____

<em>Alternate solution</em>

The difference of denominator and numerator in 2/5 is 5-2 = 3. The difference of denominator and numerator in 5/6 is 6-5 = 1. In order to make the latter difference 3, we must have (3/3)(5/6) = 15/18. We can get 15/18 from 2/5 by adding 13 to numerator and denominator.
