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).
How is subtraction like division?
It's basically the same concept. Like subtraction is the opposite of addition, and division is the opposite of multiplication. Just the reverse. Kind of hard to explain.... ask your teacher!
If a plus b equals c what does a plus c equal?
A+c= 2a+b
Are the hypotenuses equal in two right triangles if the legs are equal?
Yes, because a^2 + b^2 = c^2, where a and b are legs and c is the hypotenuse. Therefore, if a and b are equal, so will c.
If a equal 105 and c equal 67 what is b?
To solve this you need more information about the relationship between a, b and c.
How do we check weather the entered 3 characters are equal are not?
You can use if-else statements to check for equality.Eg:char a, b, c;scanf("%c%c%c", &a, &b, &c);if( a==b && b==c)printf("They are equal\n");elseprintf("They are not equal\n");
How can you upload a questionnaire for people to fill in on the internet?
if b+c/a = c+a/b = a+b/c and a+b+c not equal to 0 then show that each of these ratio is equal to 2

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 equals B and B equals C does A equal C?
Yes.
What is theorem on equal ratios?
if a/b=c/d then a+b/c+d = a/b=c/d
If a plus b equals c what does a plus c equal?
A+c= 2a+b
If a equals b and b equals c then what does c plus b equals?
2a. (a, b and c are all equal.)
Are the hypotenuses equal in two right triangles if the legs are equal?
Yes, because a^2 + b^2 = c^2, where a and b are legs and c is the hypotenuse. Therefore, if a and b are equal, so will c.
If a equal 105 and c equal 67 what is b?
To solve this you need more information about the relationship between a, b and c.
What is the difference between equals equals and equals in C programming?
a = b changes the value of a and makes it the same as the value of b. a == b does not change the values of a or b. It is an expression that is equal to 1 if a and b are the same or to 0 if a and b are different. For example: if ( a == b) { c = d;} means if a and b are the same, then set c equal to d. C does let you write the following: if ( a = b) { c = d;} This sets a equal to the value of b, and then if the new value of a is non-zero, it sets c equal to d. You can do this, but if you see a single equal sign in an "if" condition, that usually (but not always) is a mistake.
