If a equals 2b and 4b equals 6c then a equals?
a=2b 4b=6c becomes 2b=3c a=3c
What is 4a x 4b equals?
4a x 4b = 16ab Variables can be multiplied just like numbers.
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 4a 2b a?
4a+2b+a
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.
