En una tienda se anuncia la rebaja de 20% en todos sus artículos. Rafael elije una camisa y al llegar a la caja le informan que esa camisa, por traer etiqueta roja, cuenta con un descuento adicional del 15%. Si Rafael pago $510.00, ¿cual era él precio de la camisa sin los descuentos?

Answers

9514 1404 393

Answer:

  $750

Step-by-step explanation:

The 20% discount multiplies the price by (1 - 20%) = 0.80.

The 15% discount multiplies the price by (1 - 15%) = 0.85.

After applying the discounts to the initial price P, we have ...

  P(0.80)(0.85) = $510

  P = $510/(0.80·0.85) = $750

The price before discounts was $750.

The difference between two whole numbers is 9. Twice the smaller number is 6 more than the larger. What is the smaller number?

Answers

Answer = 3
Explanation:
27/3= 9
3x2= 6

The smaller number is 15

let

the larger number = x

the smaller number = y

Therefore,

The difference between the two whole numbers is 9 can be express as follows:

x - y = 9

Twice the smaller number is 6 more than the larger. Therefore,

2y = x + 6

Combine the equation.

x - y = 9

-x + 2y = 6

y = 15

x - 15 = 9

x = 9 + 15

x = 24

Therefore,

The larger number = 24

The smaller number = 15

Answer:

D. x = 3

Step-by-step explanation:

We would like to find out for what value of x does f(x) = g(x). This is essentially the same as asking us to find the x-value for which f(x) = k, where k is some number, and g(x) = k, as well.

Looking at the two tables provided, we notice that when x = 3, both f(x) and g(x) equal -2. So, the answer is D.
