Answer:

Fourth option

Step-by-step explanation:

The answer is the fourth option "difference of squares method." It's not the first option because the substitution method is when you pick one of the equation in a system of equations, solve it for a variable and then plug the variable into the other equation to help solve. It's not the second option because the graphing method is used to solve a system of equations by graphing the equations on the same coordinate plane, it's not the third option because the addition method is also known as the elimination method which is the third method to solving a system of equations. Therefore your answer is the fourth option.

Hope this helps.

You need to put your reindeer, Rudy, Ezekiel, Gloopin, Bloopin, and Prancer, in a single-file line to pull your sleigh. However,

topjm [15]

If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times. Similarly Rudy and Bloopin will be together 4!=24 times. So the number of ways they are not together is 120-24-24=72 ways.

Which of the following will be equal to 1⁄4?

docker41 [41]

Answer:

C - 100% of 0.25

Step-by-step explanation:

This answer is basically the same as 25% of 100, just worded differently to confuse you.

25 is 1/4th of 100, so this should be the answer. :)

If you're curious of what the other answers amount to:

One hundredth of 250 = 2.5

50% of 5 = 2.5

40% of 1 = 0.4
