What is 5ab plus 4a-b-2ab plus 5b?
5ab-2ab+4a-b+5b = 3ab+4a+4b
What expressions are equal to 4(a plus b)?
4a + 4b is one possible answer.
What does ab over b divided by 4a over 5b equal?
(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
2a-4b plus 4b-6a equals a plus b?
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
What is b plus b plus b plus b?
4b.
What is b plus b plus b plus b equals?
4b
Simplify b plus b plus b plus b?
4b
How do you solve 4b plus 3 equals 15?
4b + 3 = 15 First, Subtract 3 from both sides. -3 -3 4b = 12 Then, divide by 4 to get b by itself. 4 4 b = 3
What is a plus a plus a plus a plus b plus b?
a+a+a+a+b+b - add the like terms =4a+2b 4a and 2b cannot be added because they are not like terms.
3a 4b equals 7a 4b?
Clearly, there are some signs missing. So let's try the four possibilities for the second terms: 1. + and + 3a + 4b = 7a + 4b Subtract 4b from each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 2. + and - 3a + 4b = 7a - 4b Subtract 4b from each side: 3a = 7a - 8b Subtract 7a from each side: -4a = -8b or 4a = 8b Answer: a = 2b 3. - and - 3a - 4b = 7a - 4b Add 4b to each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 4. - and + 3a - 4b = 7a + 4b Add 4b to each side: 3a = 7a + 8b Subtract 7a from each side: -4a = 8b or 4a = -8b Answer: a = -2b Can't do better than that with the information available.
What is the answer to 4b plus b?
5b
A-b plus a-b plus 2b plus 2a?
