Answer:

34

Step-by-step explanation:

\frac{2}{5}*85

Long way

  1. multiply the two numerators
  2. multiply the two denominators
  3. simplify the new fractions

\frac{85}{1}*\frac{2}{5}  \\ \\ \frac{170}{5} \\ \\ =34

short way

-can be simplified before mulitplying

  1. factor out common factors in the numerator and denominator

\frac{85}{1} *\frac{2}{5} \\ \\ \frac{17}{1}*\frac{2}{1} =34

Think 85 and 5 as nickels. You need 20 nickels to make 100. Subtract 100 by 85 to get 15. You get 3 nickels and 17 nickels. 17 is the common factor. Multiply 17 by 2 to get your answer.

Answer:

x =  - 12

C.E.: x <em>=/=</em> -4

Step-by-step explanation:

\frac{x}{x + 4}  =  \frac{4}{x + 4}  + 2 \\  \frac{x}{x + 4}  =  \frac{4 + 2x + 8}{x + 4}  \\ x = 4 + 2x + 8 \\  - x = 12 \\ x =  - 12
