Let x denote the count of $5 bills and y signify the count of $10 bills. It can be stated that "the number of $10 bills is twice the number of $5 bills." Thus, y is 2 times x. We can formulate an equation, y = 2x (equation 1). The total value of all bills amounts to $125, allowing us to create another equation: 5*(number of $5 bills) + 10*(number of $10 bills) = 125. That leads to the equation 5(x) + 10(y) = 125 (equation 2). By substituting y = 2x into equation 2, we get 5(x) + 10(2x) = 125. This simplifies to 5x + 20x = 125. Combining like terms yields 25x = 125. Dividing both sides by 25 results in x = 5. By substituting x = 5 in the first equation, we find y = 2(5) = 10. Consequently, there are 5 $5 bills and 10 $10 bills.
Detailed explanation:
Question 4 provides clear information,
thus resolving Question 4:
1 euro equals $1.17.
Consequently, €20.46 is calculated as 20.46 multiplied by 1.17, which equals $23.93.
1 pound equals $1.28.
Thus, £12.60 translates to 12.60 multiplied by 1.28, yielding $16.128.
Therefore, the MP3 in pounds is $7.81 cheaper in dollars.
Respuesta:
126 pies
Explicación paso a paso:
Dado que:
Ecuación de la línea que representa el sendero de naturaleza:
y = 13x - 4
Distancia del gazebo respecto al sendero de naturaleza:
Cada unidad en el plano de coordenadas = 10 pies
Por lo tanto,
y = 13(10) - 4
y = 130 - 4
y = 126 pies
To tackle this problem, you can use the same method from the prior situation.
Option 1: 2/(1/16 + 1/65) = 25.7 mpg
Option 2: 2/(1/14 + 1/85) = 24.0 mpg
