6 === the what does B =
A:B = 3:4 = 9:12 B:C = 6:5 = 12:10 So A:B:C = 9:12:10
Yes.
2a. (a, b and c are all equal.)
No, they are not equal sets.
It equals 10.5 A = 6 B = 8 which is 6+1/3 of 6 C = 10.5 which is 8+1/3 of 8
b = -6
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.
really easy question a=6 , b=8 , c= 10
Commutative, not communtative The mathematical property of being able to change the order of the numbers and not change the answer. A plus B equals B plus A (1 plus 3 equals 4, 3 plus 1 equals 4) A times B equals B times A (2 times 5 equals 10, 5 times 2 equals 10) Addition and multiplication are commutative operators A minus B is not necessarily equal to B minus A (6 minus 4 equals 2, 4 minus 6 equals minus 2) A divided B is not necessarily equal to B divided A (9 divided by 3 equals 3, 3 divided by 9 equals one-third) Subtraction and division are not commutative operators
6 === the what does B =
Taking it step by step: 2b - b - 10 = -13 b - 10 = -13 b = -13 + 10 b = - 3
As your question implies, the quadratic formula. You know your a,b and c already. X = - b (+/-) sqrt(b2- 4ac)/2a X = - 10 (+/-) sqrt[102 - 4(3)(8)]/2(3) X = - 10 (+/-) sqrt(100 - 96)/6 X = - 10 (+/-) sqrt(4)/6 X = [- 10 (+/-) 2]/6 --------------------------- X = - 4/3 and X = - 2
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).
A:B = 3:4 = 9:12 B:C = 6:5 = 12:10 So A:B:C = 9:12:10
b = 6
Whan a = 2 and b = 6, 5a + 2b = 5*2 + 2*6 = 10 + 12 = 22
