The solution to the Raoul's equation x² - 6x - 27 = 0 is x = 9; or x = -3

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation:

x² - 6x - 27 = 0

Adding 27 to both sides:

x² - 6x - 27 + 27 = 0 + 27

x² - 6x = 27

Adding to both sides the square of half the coefficient of x, that is 9:

x² - 6x + 9 = 27 + 9

(x - 3)² = 36

taking square root of both sides:

√(x - 3)² = √36

x - 3 = ±6

x = 3 ± 6

x = 3 + 6 or; x = 3 - 6

x = 9; or x = -3

The solution to the Raoul's equation x² - 6x - 27 = 0 is x = 9; or x = -3

A water tank holds 621 gallons but is leaking at a rate of 4 gallons per week. A second water tank holds 828 gallons but is leak
hram777 [196]

Answer:

69 weeks

Step-by-step explanation:

Let the number of weeks be x.

The first tank holds 621 gallons is leaking at a rate of 4 gallons per week. This means that after x weeks, the amount of water in the tank is:

621 - 4x

The second tank holds 828 gallons is leaking at a rate of 7 gallons per week. This means that after x weeks, the amount of water in the tank is:

828 - 7x

After a certain amount of weeks, the amount of water in both tanks is the same. That means that:

621 - 4x = 828 - 7x

=> 7x - 4x = 828 - 621

3x = 207

x = 207 / 3 = 69

This means that the amount of water in the tank will be the same after 69 weeks.

Approximate √60 to the nearest tenth with step by step directions please! And thanks!
MA_775_DIABLO [31]

Answer:

7.7 is the answer

Step-by-step explanation:

(credit to manics.info)

Step 1:

Calculate the square root of 60 to be:

√60 = 7.74596669241483

Step 2:

Reduce the tail of the answer above to two numbers after the decimal point:

7.74

Step 3:

Round 7.74 so you only have one digit after the decimal point to get the answer:

7.7

To check that the answer is correct, use your calculator to confirm that 7.72 is about 60.

Hope this help and have a great day!
