Which Expression Is Equivalent To 4Y 2

Let us evaluate the expressions for some values of and. Step 2: Click the blue arrow to submit and see the result! Example 4: Consider the first expression for any non-zero values of the variable. I am confused where did the (4-1) come from? Which expression is equivalent to 2g3. So I have 5x-- that's that term-- minus 2x. Well you are just add the X's to the numbers like this (the first number is the coefficient btw)2x +4X = whatever the answer would be. And your goal is to try to simplify it as much as you can.

• Which expression is equivalent to 2g3
• Which expression is equivalent to 4g3h2k4
• Which expression is equivalent to 4y 2
• Which expression is equivalent to 4y2 3y2
• Which expression is equivalent to 3b 2r 4b r.o

Which Expression Is Equivalent To 2G3

There's not some fancy algebraic magic going on here. Why do i hate khan(4 votes). This happens around2:50to3:00(6 votes). And it said the answer is this: 4t-t+2=(4-1)t+2. Good Question ( 61). Do you feel like you are improving or just getting by?

Which Expression Is Equivalent To 4G3H2K4

All these expressions have the same value, whenever the same value is substituted for. This simplified to 3x plus 10y plus 7z plus 5. Step 3: Finally, the equivalent expression for the given algebraic expression will be displayed in a new window. When, the expression is not defined. Combine the like terms of the second expression. Which expression is equivalent to 4g3h2k4. They're the number that you're multiplying the variable by. Now let us consider some expressions that include variables, say. Question: Write the equivalent expression for the given expression: 3x+9.

Which Expression Is Equivalent To 4Y 2

We added the coefficients-- 7 plus 3-- to get 10y. First, it was in the right order and then Sal changed the order to gather same species. It's much more if you've got 7 of something, you add another 3 to that something, you've got 10 of that something. The coefficient on 3y is 3. And then the last term that I haven't included yet is that plus 5. When there is an equation like this -4q - (-8q) +10, where there is a minus sign in front of the brackets, the sign(s) inside the brackets get changed. Subtracting a z is the exact same thing as subtracting 1z. Which expression is equivalent to 3b 2r 4b r.o. We can re-group the right side of the equation to or or some other combination. Here, the terms and are like terms. Now, in a lot of algebra classes, you'll hear people say, oh, well, you know, the coefficient on 5x is 5. And then you could see, oh, yeah, you definitely did add the two coefficients, the 8 and the negative 1. You have to make sure that you're adding and subtracting the same things. The first expression is the sum of 's and 's whereas the second one is the sum of 's and 's.

Which Expression Is Equivalent To 4Y2 3Y2

How would, for example 2z-7-1 = 2z + 8(4 votes). Crop a question and search for answer. What is an Algebraic Expression? Only you can answer that, what is your attitude toward Math in general? So, there is at least one pair of values of the variables for which the two expressions are not the same. The calculator works for both numbers and expressions containing variables. Let's just think about it, step by step. Take 3 outside from the expression, we get, = 3(x+3), which is called the equivalent expression.

Which Expression Is Equivalent To 3B 2R 4B R.O

But if the values are plugged in the expression, both the expressions give the same result. Similarly, in mathematics, the equivalent expressions are the expressions that are the same, even though the expression looks different. That is, they are equivalent expressions. No, the number wont get more negative. We have a hairy-looking expression here. I don't see any number out front of the z.

Then i have plus 8z, and then I have minus z. And it might help if we were to actually reorder the terms in this expression. I cannot answer your question. Here, we're dealing with x's. They are not equivalent in general. We're going to simplify this expression together putting to use our new knowledge of how to combine like terms. If I have 5 x's and I were to take away 2 x's, is how many x's am I going to be left with? We can't think about merging the x's and the y's, at least not in any simple way right now, because that, frankly, wouldn't make any intuitive sense.

Feedback from students. Enjoy live Q&A or pic answer. So if I have 2x + 3y + 4z - x - 2y - 3z, I can rearrange that to 2x - x + 3y - 2y + 4z - 3z. Here is one perspective on this Ted Talk - "Why is X the unknown, (12 votes). Step 1: Enter the expression you want to simplify into the editor. So i'm confused with this question: Combine the like terms to create an equivalent expression. If you have 5 of something, you take away 2 of that something, you are left with 3 of that something. That's true of anything. Let me write that word down-- coefficient.

That is, the expressions are equivalent except when. Now let's look at the z's.
