Solve for x over the real numbers: by completing the square:
5 x^2 - 30 x = 5
Divide both sides by 5:
x^2 - 6 x = 1
Add 9 to both sides:
x^2 - 6 x + 9 = 10
Write the left hand side as a square:
(x - 3)^2 = 10
Take the square root of both sides:
x - 3 = sqrt(10) or x - 3 = -sqrt(10)
Add 3 to both sides:
x = 3 + sqrt(10) or x - 3 = -sqrt(10)
Add 3 to both sides:
Answer: | x = 3 + sqrt(10) or x = 3 - sqrt(10)
Total pounds of 2.5 pounds of raspberries and 2 pounds of kiwi bought is 4.5 pounds.
Total pounds of 2 pounds of raspberries and y pounds of kiwi is (2 +y) pounds.
In order to determine the total pounds of fruits Ellie buys, the pounds of raspberries bought would be added to the pounds of Kiwi she bought.
Addition is the process of determining the total value of two or more numbers by adding the numbers together. It is one of the basic mathematical operations.
Total pounds Ellie bought when she buys 2.5 pounds of raspberries and 2 pounds of kiwi: 2.5 + 2 = 4.5 pounds.
Total pounds Ellie bought when she buys 2 pounds of raspberries and y pounds of kiwi: 2 + y = (2 +y) pounds.

Answer:
Variación de temperatura: 310°C
Step-by-step explanation:
La variación de temperatura entre la temperatura más baja conocida en la tierra (-273°C = 273° bajo cero) y la temperatura promedio de la tierra (37°C) será el valor absoluto de la diferencia de estos dos valores, es decir:
Variación de temperatura: |-273°C - 37°C|
Variación de temperatura: |-310°C|
<em>Como el valor absoluto de un número negativo es su valor positivo (|-x| = x)</em>
<h3>Variación de temperatura: 310°C</h3>
