Simplify this 6x-3y-z+2x+3y-7z

Mathematics

Answer:

8x - 8z.

Step-by-step explanation:

Let's first rearrange 6x-3y-z+2x+3y-7z where all the x's are together, all y's together, and all z's are together:

6x +2x + 3y - 3y - z - 7z.

First we combine like terms.

6x + 2x ⇒ 8x

3y - 3y ⇒ 0

z - 7z   ⇒ -8z.

Since the y's result in 0, we do not include them.

Therefore, our answer is 8x - 8z.

Zoltan has a list of whole numbers, all larger than 0 but smaller than 1000. He notices that every number in his list is either
timama [110]

The largest number of different whole numbers that can be on Zoltan's list is 999

<h3>How to determine the largest number?</h3>

The condition is given as:

Number =  1/3 of another number

Or

Number = 3 times another number

This means that the list consists of multiples of 3

The largest multiple of 3 less than 1000 is 999

Hence, the largest number of different whole numbers that can be on Zoltan's list is 999

Which measure is of an angle that is conterminal with a 95 degree angle
timofeeve [1]

Answer: Choice B

95 - 1080n for any integer n

=================================================

Explanation:

Notice how 1080 is a multiple of 360 since 360*3 = 1080. The other values 1450, 780 and 340 are not multiples of 360. For example 1450/360 = 4.02777 approximately. We need a whole number result to show it is a multiple.

Therefore, choice B shows subtracting off a multiple of 360 from the original angle 95. In my opinion, it would be better to write 95+360n or 95-360n to make it more clear we are adding or subtracting multiples of 360.

Choice B will find coterminal angles, but there will be missing gaps. One missing coterminal angle is 95-360 = -265 degrees. So again, 95-360n is a more complete picture. I can see what your teacher is going for though.
