What does ab equals 1a plus 1B plus ab equal to?
ab=1a+1b a is equal to either 0 or two, and b is equal to a
1a - 1b c solve for a?
0
What is the product of the reciprocal from 1a and 1b is?
It is 1/(ab).
Is algebra foundations 2 and algebra 1B the same thing?
Depends. Most of us would not know what "Algebra Foundations 2" or "Algebra 1B" are, since the name of such a course is probably determined by the school or local district. Compare the curricula of both courses to see if they are the same.
Write a rule to determine when a number is divisible by 12?
A number is divisible by 12 if it is divisible by 3 AND it is divisible by 4. Rule 1a (Divisibility by 3): Add up all the digits of the number. Is this number divisible by 3? Rule 1b (Divisibility by 4): Is the number formed by the last two digits of the original number (the number left after deleting the hundreds, thousands, millions etc) divisible by 4? If the answer to 1a is NO, then the number is not divisible by 3 and so not divisible by 12. In this case, obviously, rule 1b is irrelevant. If the answer to 1b is NO, then the number is not divisible by 4 and so not divisible by 12. If the answer to both 1a and 1b is YES, then the number is divisible by 12.
