Answer:

B. $\frac{6}{2x^{2} - 5x}$

Step-by-step explanation:

The product of the ratioal expressions given above can be found as follows:

$= \frac{2}{x} * \frac{3}{2x - 5}$

Multiply the denominators together, and the numerators together, separately to get a single expression

$\frac{2(3)}{x(2x - 5)}$

$= \frac{6}{x(2x) - x(5)}$

$= \frac{6}{2x^{2} - 5x}$

The product of the expression $\ = \frac{2}{x}*\frac{3}{2x - 5}$ = $\frac{6}{2x^{2} - 5x}$

The answer is B.

At a particular restaurant, each pizza roll has 60 calories and each mini hotdog has 70 calories. A combination meal with pizza

PolarNik [594]

Answer:

There are 9 pizza rolls and 12 mini hotdogs in the meal.

Step-by-step explanation:

We are given the following in the question.

Let x be the number of pizza rolls sold and y be the number of mini hotdogs in the combination meal.

Total number of items in combination meal = 21

Thus, we can write the equation:

$x + y = 21$

Calorie in a pizza roll = 60

Calorie in a mini hotdog = 70

Total calories = 1380

Thus, we can write the equation:

$60x + 70y = 1380$

Solving the two equations, we get,

$60x + 70y - (60x+60y) = 1380 - 60(21) \\10y = 120\\\Rightarrow y = 12\\\Rightarrow x = 21-12 = 9$

Thus, there are 9 pizza rolls and 12 mini hotdogs in the meal.
