Well now all you have to do is divide 6000 by 3 and that will tell you how many minutes will lapse. 6000 gals / 3 gals per minute this will leave you with 2000 minutes because the gals divide out

square root of -25 (answer)

The answer to this problem is not a real number. In order to get a square root of a negative number we use the letter (i). (i) is not a variable. It is similar to pi it has a value. The value of i = √-1. √-25 First of all you have to...

Problem 1: Use the FOIL method (2x + 1)(3x - 1) = 6x^2 - 2x + 3x - 1 = 6x^2 + x - 1 Problem 2: Use the formula y = mx + b. m is your slope. y = -2x + b. Now plug in your coordinates into the x and y and solve for b. -5 = -2(3) + b -5 = -6 + b 1 = b so...

4(x + 6) = 6(x - 2) (answer)

4(x + 6) = 6(x - 2) Distribute the 4 and the 6 4x + 24 = 6x - 12 Subtract 24 from both sides 4x = 6x - 36 Subtract 6x from both sides -2x = -36 ...

3(x-4)-6(x-5) (answer)

The first step in this process is to distribute the constants in front of the paraetheses. Now when you work with the 6 it will distribute as a -6. 3(x - 4) - 6(x - 5) = 3x - 12 - 6x + 30 Now combine like terms -3x + 18 or 18 - 3x

b(2)+5b+6=0 (answer)

In order to solve this equation you have to factor. b^2 + 5b + 6 = 0 (b + 2) (b + 3) = 0 Now what values of b will make this equation true? Remember anything multiplied by 0 = 0. b = -2 or -3 Here's why. Plug -2 into the equation. (-2 + 2) (-2 + 3)...

A denominator is the number on the bottom in a fraction. In this case, 9 and 12 are both whole numbers. The common denominator would be 1 because both numbers would have a fraction of 9/1 and 12/1. However, if 9 and 12 are denominators to fractions (i.e. 1/9 and 1/12) that would be a different story...

What animals are self aware? (answer)

The most common test for finding out if an animal is self aware is what is known as the mirror test. If an animal is able to identify itself in a mirror, that is a sign that the animal is self aware. Most domestic pets are not self aware. For example: If you were to place a mirror in front of a...

This particular answer works out to be undefined because it is a straight line and there is no slope and no equation for it. I will show you how to work it out though so you will know how to do it with other problems. We will still be using the y = mx + b formula. First step is to find m. In...

Same thing here only this time you will have a b value. Remember our formula is y = mx + b. First step is to place the slope into your formula. y = 5x + b. Now we have to figure out what the value of b is. Since the x value given is not 0, it requires a little more work to figure out. Simply...

For a line that passes through the origin (0,0) the process is very simple. The slope-intercept formula for a line is y = mx + b, where m is equal to the slope and b is the y-intercept. Since your line is passing through the origin, the y-intercept is 0. This means all you have to do is add...

What exactly is the problem to be solved?

Where x = the age of Jimmy (x - 3) + x = 21 combine the x values 2x - 3 = 21 move the -3 over to the right hand side of the equations by using the opposite mathematical symbol 2x = 24 divide both sides of the equation by 2 x = 12 Jimmy is 12 years old and Drew...
