3a is part of an algebra equation. It mean the variable "a" time 3. to solve, you need to know the value of a. if the value of a is 5 the 3a would be 3 x 5 which is 15.
9a + 7b *remember to look and understand the letters!*
3a^2 + 3a^2 = 6a^2 3a^2 - 3a^2 = 0 3a^2 x 3a^2 = 9a^4 3a^2 divided by 3a^2 = 1
The given expression can be simplified to: 3b-a
Ah, let's take a moment to appreciate the beauty of algebra. To factorise 6ab - 9ac, we can first factor out the greatest common factor, which is 3a. This leaves us with 3a(2b - 3c), where 2b - 3c is the factored expression. Just like painting a happy little tree, we've simplified our expression with a few gentle brushstrokes.

The answer to the expression 3a + 4 depends on the value of 'a' as it is a variable. If 'a' is a specific number, you would first multiply 3 by 'a' and then add 4 to the result. For example, if 'a' is 2, the answer would be 3(2) + 4 = 6 + 4 = 10. In general, the expression simplifies to 3a + 4.
9a + 7b *remember to look and understand the letters!*

The variable.In algebra a can represent a number - any number, it does not have to have a value like 6 or 31¼ until you have worked one out.You could say, what is a if 3a + 6 = 24? Mathematicians like that kind of problem but if you learn how to solve it, it is a powerful thing that you can use for different problems.3a + 6 = 24 can also be written as 3a = 18, so a = 6 is the solution. It is also the solution to the question: what is the number that if you triple it and add 6, the answer is 24? by doing the algebra, you get the answer 6 quite quickly, but the good thing about algebra is that it gives a framework for solving much more difficult questions as well, that you can't do in your head.
3a + 2b is an expression in algebra. If you make 3a + 2b equal to something then you can find the values of "a" and "b" Lets say you make 3a + 2b equal to 23 3a + 2b = 23 Now find "a" and "b" to make this equation true... 3(5) + 2(4) = 23 15 + 8 = 23 23 = 23 Correct So in this case a=5 and b=4
Oh, isn't that a happy little math problem? When you add 3a and 7a together, you get 10a. It's just like mixing different colors on your palette to create a beautiful painting. Just remember to take your time and enjoy the process!
Your equation would look like this: .3a = 22.05 After that, it's just a matter of algebra: $73.50
3a^2 + 3a^2 = 6a^2 3a^2 - 3a^2 = 0 3a^2 x 3a^2 = 9a^4 3a^2 divided by 3a^2 = 1
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
If you mean: 4a +29 -3a -a +3a then it simplifies to 29 +3a
You divide numbers by numbers, you don't divide letters. If you are talking about algebra - where letters stand for numbers - then the answer would depend on the value of the letter a. "a" multiplied by any integer is divisible by a, for example: 0a = 0, 1a = a, 2a, 3a, 4a, 5a, -a, -2a, -3a, etc.
