f r(x) = 3x – 1 and s(x) = 2x + 1, which expression is equivalent to (StartFraction r Over s EndFraction) (6)?
Leya [2.2K]

The equivalent expression to \mathbf{(\dfrac{r}{s})(6)= \dfrac{17}{13}}

<h3>What are the equivalent expressions?</h3>

Equivalent expressions are similar expressions that may have different forms but when a value is replaced with the variables in the same form provides the same answer.

From the information given, If:

  • r(x) = 3x - 1
  • s(x) = 2x + 1

Then the fractional form can be an expression as:

\mathbf{(\dfrac{r}{s})(x)= \dfrac{3x-1}{2x+1}}

where;

  • x = 6

\mathbf{(\dfrac{r}{s})(6)= \dfrac{3(6)-1}{2(6)+1}}

\mathbf{(\dfrac{r}{s})(6)= \dfrac{18-1}{12+1}}

\mathbf{(\dfrac{r}{s})(6)= \dfrac{17}{13}}

At a sports event, 1, 045 spectators will be
raketka [301]

Answer:

85n >/= 1,045

Step-by-step explanation:

85 people times n buses has to equal or exceed 1,045 people

85n is greater than or equal to 1,045

85n >/= 1, 045

n >/= 12.29

So, since n has to be greater than or equal to 12.29, and there is no 29/100ths of a bus, they would need 13 buses (in case there's a follow-up question)

Please lmk if you have questions.
