If a is equal to b. is not a equal to not b?
No because if a=4 and b=4 then a=b and not a can equal 6 and not b can equal 5 so ~a is not = to ~b
If sum of three numbers is -4 the second number decreased by the third number is equal to the first the sum of the first and second number is -5 what are the numbers?

Two angles are complementary The first angle measures 35 What is the measurement of the second angle?
Lets assume that the first angle is A and the second angle is B. These two angles are complementary so their sum is 90. So if angle A is equal to 35, then this can be plugged into an algebraic formula: A + B = 90 (35) + B = 90 B = 55 The measure of the second angle is 55o
What does b plus b equal?
2b
Is a to the second power over b to the second power greater than a over b?
Let's reverse the question - Is a over b less than a squared over b squared? Answer - Only when a is less than b example 1: a is less than b a = 2 a squared = 4 b = 3 b squared = 9 2 / 3 = .6666 4 / 9 = .444444 2 / 3 is greater than 4 / 9 example 2: a is equal to b a = 2 a squared = 4 b = 2 b squared = 4 2 / 4 = .5 2 / 4 = .5 2 / 4 is equal to 2 / 4 example 3: a is greater than b a = 3 a squared = 9 b = 2 b squared = 4 3 / 2 = 1.5 9 / 4 = 2.25 3 / 2 is less than 9 / 4 - wjs1632 -
How does B decreased by 4 is equal to 35 look like in an algebraic expression?
Like this . . .B - 4 = 35and it is then an equation, not an expression.
If a is equal to b. is not a equal to not b?
No because if a=4 and b=4 then a=b and not a can equal 6 and not b can equal 5 so ~a is not = to ~b
If sum of three numbers is -4 the second number decreased by the third number is equal to the first the sum of the first and second number is -5 what are the numbers?

What does -a-b equal if a equals -4 and b equals 3?
1 is the answer. -(-4)- 3 = 4-3 = 1 .
The quotient of 16 and b is at most 4?
16/b .LE. 4 {the .LE. means less than or equal to, I think it's from FORTRAN, but cannot recall for sure off hand}So 16/b .LE. 4 --> multiply by b: 16 .LE. 4*b --> divide by 4: 4 .LE. b, so: b is greater than or equal to 4
What is the answer to b divided by 4 equals -9?
13
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 is an expression of 4 less than b?
An expression of "4 less than b" can be represented as b - 4. This means you are subtracting 4 from the variable b. For example, if b is equal to 10, then 4 less than b would be 10 - 4, which equals 6.
What is equivalent resistance across a and b is equal to?
r/4

How do you factor 4xˆ2 plus 27x plus 35?
4X^2 + 27X + 35 = 0 Quadratically. The discriminant says.......... 27^2 - 4(4)(35) = 169 > 1, so 2 real roots, though they may be ugly. X = -b +/- sqrt(b^2-4ac)/2a a = 4 b = 27 c = 35 X = -27 +/- sqrt[27^2 - 4(4)(35)]/2(4) X = -27 +/- sqrt(169)/8 X = [-27 +/- 13]/8 X = - 7/4 X = -5 My TI-84 graphing calculator confirms this answer
Is 27 over 35 equivalent to 3 over 4?
No, b/c 27/35 can't be simplified to 3/4, 3x9=27, but 4x9=36, not 35. 27/36 would work though
