Answer:

  12/x^5

Step-by-step explanation:

The fractions are multiplied in the usual way. The applicable rule of exponents is ...

  (x^a)(x^b) = x^(a+b)

__

  \dfrac{3}{x^2}\cdot\dfrac{4}{x^3}=\dfrac{3\cdot4}{x^2\cdot x^3}=\dfrac{12}{x^{2+3}}=\boxed{\dfrac{12}{x^5}}

marusya05 [52]
20% of 89.75 is 17.95
\frac{20}{100}  =  \frac{x}{89.75}  \\ x =  \frac{89.75 \times 20}{100} =  \frac{1795}{100}  = 17.95
so :
89.75 - 19.95 = 71.8
the Trina's coupon will subtract the answer by 10%:

10%of 71.8 is 7.18
\frac{10}{100}  =  \frac{x}{71.8}  \\ x =  \frac{71.8 \times 10}{100}  =  \frac{718}{100}  = 7.18
so the final answer is:
71.8 - 7.18 = 64.62
she has to pay $64.62
hope this helps

Jason considered two similar televisions at a local electronics store. The generic version was based off the brand name and was
slavikrds [6]

Keywords:

<em>Variables, televisions, generic version, TV brand, dimensions </em>

For this case we have two televisions, one generic version and one brand. We know that the generic version represents \frac {2} {3}the size of the brand. We must define two variables that represent the dimensions of the brand TV, so we have:

  • x: Brand TV length
  • y: Brand TV width

Dimensions of the generic TV:

Length = 12\\Width = 24

So:

\frac {2} {3} x = 12

\frac {2} {3} y = 24

By clearing the variables we have:

x = 12 \frac {3} {2} = 18\\y = 24 \frac {3} {2} = 36

Thus, the dimensions of the brand TV are 18 inches by 36 inches

Answer:

 The dimensions of the brand TV are 18 inches by 36 inches
