What is 4 x a x 3 equals?
4a x 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 5ab plus 4a-b-2ab plus 5b?
5ab-2ab+4a-b+5b = 3ab+4a+4b
If A equals 4B and A equals 20 what is B?
if i think of it, a=4b though a =20 so 20=4b 4 x 5=20 so b would equal five 4B/4=20/40 B=5 4(5)=20
What is 4a times a?
5a or 4a squared
What is 4 x a x 3 equals?
4a x 3
What is 2b x 2b equals?
Well, honey, 2b x 2b is just 4b^2. It's like math's way of saying "I see you, I got your back." So, don't you worry about a thing, because 4b^2 is the answer to your little math problem.

5ab-2ab+4a-b+5b = 3ab+4a+4b

A plus b divide by 4a plus 4b?
1/4
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)
What is maximun error of x equals 6a plus 4b where a equals 40 plus -2 and b equals 20 plus -2 after finding value of x?
2
If a equals 2b and 4b equals 6c then a equals?
a=2b 4b=6c becomes 2b=3c a=3c
What is 5b equals 21 plus 4b?
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
If the ratio of 4a to 3b is 8 to 9 what is the ratio of 3a to 4b?
1/2
