Responder:
Número de bueyes = 12
Número de vacas = 24
Explicación paso a paso:
Dado que :
Número de vacas compradas = 2 veces el número de bueyes;
Sea número de bueyes = y
Número de vacas = 2 años
Costo de la vaca = 70
Costo de bueyes = 85
Costo total = 2700
Por lo tanto;
(2 años * 70) + (y * 85) = 2700
140 años + 85 años = 2700
225 años = 2700
225 años / 225 = 2700/225
y = 12
Número de bueyes = y = 12
Número de vacas = 2y = 2 * 12 = 24
The answer is They left a 20% tip, so the service was probably above average. First step is to the amount of the sales tax. If 100% is $73.89, 5.8% will be x (tax): 100% : $73.89 = 5.8% : x. x = $73.89 * 5.8% : 100%. x = $4.28. Now, we have the price for meals, sales tax, and the total amount of money left, so we can calculate how much the tip is: $93.00 - $73.89 - $4.28 = $14.83. So, the tip is $14.83. Let represent it as percent. If $73.89 is 100%, $14.83 will be x. $73.89 : 100% = $14.83 : x. x = $14.83 * 100% : $73.89. x = 20%. So, they left a 20% tip, so the service was probably above average.

The answer, when rounded to the nearest tenth is 19.2
First you can get rid of the decimals by multiplying both numbers by 100, this just makes the whole problem easier. Now all that needs to be done is long division:
(In my work I didn’t realize that it said round to the nearest tenth until I had already gotten past what I needed to find)

Answer:
1,-1,3,-3
Step-by-step explanation:
your P is the first number or the number with the highest exponent, your Q is the last number or the number with no variables. So you make a list of what multiplies to your P's and what multiplies to your Q's and you divide your P list by Q. So 3 is made by -1,1,-3,3 and -1 is made by -1,1. So dividing that you get your list of -3,-1,1,3
