How can you find the sum of 2z-20 and 3z plus 5?
Add like terms to like: (2z - 20) + (3z + 5) = (2z + 3z) + (-20 + 5) = 5z - 15 2z is shorthand for z+z, 3z is shorthand for z+z+z, so: 2z + 3z = (z+z) + (z+z+z) = z+z+z+z+z = 5z Or, to put it another way, just add the coefficients: 2z + 3z = (2+3)z = 5z.
What is the LCM of 3z and 9z?
Since 9z is a multiple of 3z, it is automatically the LCM.
What is 3z divided by 2 which equals 9?
If 3z/2 = 9 then the value of z is 6
How do you simplify an algebraic expression?
Ex. 5x-2y+3z-2x-y+4z Alright so this is how i do it: I circle all the ones that have the x as variables and are like terms. (you don't have to do this, but i find it helps and makes it go faster) So i would have circled 5x and -2x because the sign in front of the term is with the term. Then i would have added together the two terms and that would end up being 3x because 5x plus -2x is 3x. and i write 3x down below. then i would have gone to the next thing in the problem which would be the y's. -2y and -y. when added together it is -3y. so i write -3y below with 3x so it should be 3x-3y. Then i go to the z's. 3z and 4z. 3z+4z is 7z. so i write that below. so far it should be: 3x-3y+7z because 7z is positive. And that is your final answer because you can't simplify any more because they are not like terms.
Combine 8x plus 5z minus 4x plus 3z plus 6?
8x + 5z - 4x + 3z + 6 = 8x - 4x + 5z + 3z - 6 = 4x + 8z - 6
Simplify expression 3 3z - 4 - 20 z - 5?
33z - 4 - 20z - 5 simplified would be 13z - 1.
What is the rational expression of 1 divided by 3z plus 5?
The expression written in the question is the rational expression.
Simplify 2y plus y plus 3z-z?
3y+2z
What is the answer for adding polynomials 2z plus 3z plus 5z plus 4 plus 6x-2x?
We can simplify this expression by combining the like terms. Here the likes terms are the z's and the x's.2z + 3z + 5z = 10z. (If we have 2 of something and add three of the same thing and then 5 of the same thing we will end up with 10 of that thing).Likewise we can combine the x's.6x - 2x = 4x. (You could think of this as 6x + - 2x if this helps with the idea of "combining".)Therefore we are able to simplify this expression as:2z + 3z + 5z + 4 + 6x - 2x = 10z + 4 + 4x.

How do you write an algebreic expression with 5 less than 3 times a number z?
3z-5
What is 2(3z-7) plus 5(2z plus 5)?
It is an algebraic expression that can be simplified to: 16z+11
- 47 plus 6z equals 3z - 2 what does z equal?
-47 + 6z = 3z-2-3z -3z-47 + 3z = -2+47 +473z = 45/3 /3z = 15
15 equals 3z-6 the answer?
15 = 3z - 6 15 + 6 = 3z 3z = 21 z = 7
