5........is this really a question? when b=5, then b=5

3 times 6 is 18 2 times 5 is 10 18 plus 10 is 28

a = 1

y = (3 X 8) - 5 = 21.

If: b/5+b/3 = 10 then b works out as 18.75

-2

Unfortunately, limitations of the browser used by WA means that we cannot see some symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. Do you want the value of a/b or a+b or what?

Whan a = 2 and b = 6, 5a + 2b = 5*2 + 2*6 = 10 + 12 = 22

We are given that a + b = -7 and b = 10 Therefore a +10 = =7 Subtract 10 from each side So a + 10 - 10 = -7 + 10 Which simplifiesn to a = 10 - 7 So a = 3

3a + 2b = (3*6) + (2*5) = 18 + 10 = 283a+2b= (3x6)+(2x5)= 18+10=28

Answer: Most likely there is always difference. Often A and B are describing unknown numbers. For example if A=10 and B=5. A-B = 10-5 = 5 B-A = 5-10 = -5 Answer: It can be any of these (most likely A - B), or it can be the absolute value of A - B (which is the same as the absolute value of B - A).

it can be any number since A and B (5+5 3+7 -4+14 etc) since both variables in this case. However if they give the value of B you can solve it.

-5a + b = 2 AND -a - 5b = 0 -5a + b = 2 b = 2 + 5a *using above -a - 5b = 0 -a - 5(2 + 5a) = 0 -a - 10 - 25a = 0 -26a = 10 a = 10/-26 *using 'a' value 5a + b = 2 5(10/-26) + b = 2 -25/13 -2 = -b b = 51/13 Therefore a = 10/-26 b = 51/13

a b means return true if the value of a is equal to the value of b, otherwise return false. a = b means assign the value of b to the variable a.

-5 + 10b = -3110b = -26b = -2.6

If a equals 3 and b equals minus 5 then a minus b equals what

We cannot know.

A:B = 3:4 = 9:12 B:C = 6:5 = 12:10 So A:B:C = 9:12:10

a + c - b = 3 + 2 - 5 = 5 - 5 = 0

b = 5, 10, 15, 20 or 25
