34kurt

Answer:

1 \frac{1}{15}

Step-by-step explanation:

<em>Hey there!</em>

<em />

Well when dividing fractions you need to use Keep, Change, Flip.

\frac{8}{6} / \frac{5}{4}

Keep, Change, Flip

\frac{8}{6} * \frac{4}{5}

\frac{32}{30}

Simplified

16/15

1 \frac{1}{15}

<em>Hope this helps :)</em>

Leto [7]

Answer:

b. g(x) = 12x+10

c. x = 9/2

Step-by-step explanation:

b. g(2x+1)=6x+4

   g(2x+1) = 6(2x+1)+4

   g(2x+1) = 12x+6+4

   g(2x+1) = 12x+10

    g(x) = 12x+10

c. g(x) = 64

   12x+10 = 64

     12x = 54

      x = 54/12

      x = 9/2

D.) 2.13 < 2.3 is correct. This is stating that 2.3 is greater than 2.13, which is true. In the other possible answers, for example 4.15 > 4.51, this would be false because 4.15 is not greater than 4.51. The open end of the greater than or less than sign will always point to the bigger number.
