What expressions are equal to 4(a plus b)?
4a + 4b is one possible answer.
2a-4b plus 4b-6a equals a plus b?
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
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.
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
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 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.
Evaluate -4a plus b -10a divide b when a equals 8 and b equals 5?
Evaluate -4(a+b) - 10a/b when a=8 and b=5
What is the answer to 4b plus b?
5b
