How do you know a fraction is equivalant to another fraction?
Fractions A/B and C/D are equivalent if the cross-multiples are equal. That is, is A*D = B*CFractions A/B and C/D are equivalent if the cross-multiples are equal. That is, is A*D = B*CFractions A/B and C/D are equivalent if the cross-multiples are equal. That is, is A*D = B*CFractions A/B and C/D are equivalent if the cross-multiples are equal. That is, is A*D = B*C
If a divides b and b divides a then a is equal to b?
If a divides b and b divides a then either a is equal to b or a is equal to -b. Additional note: if a divides b, there exist a p such that ap=b. and if b divides a, there exist a q such that a=bq. then ap=(bq)p=b => b(1-pq)=0 => pq=1 since b!=0 => p=q=1 or p=q=-1 => a=b or a=-b
Can you a rule for the perimeter of a rectangle where b is equal to base and h is equal to height?
2(b+h)
Why division is not commutative property?
It is because a/b does not necessarily equal b/a. If this were true, then a2 = b2, which implies a = +/- b, which does not have to be true.Likewise, subtraction is not commutative, because a-b does not have to be equal to b-a. Here, subtraction is anticommutative because a-b = -(b-a).
For real numbers a and b when is the equation a plus b equals a-b true?
a + b = a - bSubtract a from each side:+ b = - bThe only way that 'b' can equal its own negative is if b=0.So (a + b) can equal (a - b) only if b=0.(It doesn't matter what 'a' is.)
If a is equal to b then not a is equal to not?
A = B !A = !B So Not A = Not B
If a is equal to b then is not a equal to not b?
the Answer is Sometimes
Are division and subtraction commutative and associative?
No.Neither are commutative: a - b does not equal b - a, and a/b does not equal b/a.Neither is associative: (a - b) - c does not equal a - (b - c), and (a/b)/c does not equal a/(b/c).Examples of these are:4 - 2 does not equal 2 - 4.1/3 does not equal 3/1.(6 - 5) - 1 does not equal 6 - (5 - 1).(10/2)/2 does not equal 10/(2/2).
What does negative b squared equal to?
It's equal to positive b squared, or (b x b) .
If a is equal to b then not a is equal to not b?
yes. you are right. both parts of the question has to be equal.
Does addition and subtraction of vectors obey the commutative law?
Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.Addition does. Subtraction, just as with numbers: a - b is not equal to b - a, but you can change a - b to -b + a.
How do you write a less than or not equal to b?
if a is less than and not equal to b, it is written a < bIf a is less than or equal to b, it is written a ≤ b
If a is equal to b... then is not a equal to not b?
Yes. I'm assuming this is talking asking about boolean logic (the question makes little sense otherwise). If a and b are equal, then the complement of a and the complement of b are equal.
What does a squared plus b squared equal?
(a+b)(a+b)Also equal to a2+2ab+b2
What is the program for compare two strings using conditional operator in java?
System.out.println(a.equals(b) ? "They are equal" : "They are different");System.out.println(a.equals(b) ? "They are equal" : "They are different");System.out.println(a.equals(b) ? "They are equal" : "They are different");System.out.println(a.equals(b) ? "They are equal" : "They are different");
What does B to the 4Th power equal?
B4 or B*B*B*B
What does b plus a plus b-a equal?
b + a + b - a = 2b
