-8a + 3a = (-8 + 3)a = (5)a = 5a
What is the solution of -2a plus 3a plus 5b
"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."
Well if you are adding you would have 8a+2b subtract you would have -2a+2b
It can be simplified to: 3a^2 +10a+7 or factored as (3a+7)(a+1)
The given expression can be simplified to: 3b-a
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
8a+2b
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
5x - 8a + 4a - 2x + a = 3x - 3a
To simplify the expression (3a + 6b + 8a + 5b), you can combine like terms. The terms with (a) are (3a) and (8a), which add up to (11a). The terms with (b) are (6b) and (5b), which combine to (11b). Therefore, the simplified expression is (11a + 11b).
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
it could be anything. What is a? if it is 3 then you do 4x3=12+3x3=9+3=24 * * * * * It is 8a.
So we have 5a + 11 + 3a - 7 = -4 Start by combining common terms such as the 5a and 3a to give you 8a and 11 and -7 to give you 4. So now your equation is 8a + 4 = -4. Subtract 4 from both sides gives you 8a = -8. Divide -8 by 8 to give you a = -1, your solution.
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
Well, honey, if you've got 5 apples and you take away 3 apples, you're left with 2 apples. Then if you subtract another 8 apples, you're in the negative with -6 apples. So, the answer is -6a. Hope that clears things up for ya!
The block in the periodic table that consists of elements in groups 3A through 8A is the p-block.
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
