If a equals 2b and 4b equals 6c then a equals?
a=2b 4b=6c becomes 2b=3c a=3c
What is 2b x 2b equals?
4b^2
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

-2b plus 8 - 4b equals -5 - 11b plus 7?
-2b+8-4b = -5-11b+7 -2b-4b+11b = -5+7-8 5b = -6 b = -6/5
What is 4a 2b a?
4a+2b+a
What are the 6 different pencil cases?
This are the 6 different pencil cases: '''2B, HB, 4A, 4B, 2A, 4C.'''
What is the difference between the 4B and the 6B?
2B 2B or not 2B, that is the question.
What is the simplified expression of 7h 7h 2b 2b 4h -2b?
18h+4b-2b
Difference between the 4B and the 6B?
2B or not 2B, that is the question.
How do you Simplify 9 2b 4a?
2b+b-4
How do you solve b plus b plus 18 equals 4b?
I ask my 11 year old son. 2b + 18 = 4b Subtract 2b form each side: 18 = 2b Divide each side by 2: 9 = b which is the same as b = 9, but you knew that, didn't you?
