What is 12b minus 9 plus 2b minus b equal negative 87?
A minus and a minus (-4+-5) is a minus. It only becomes a plus if two minus's are timesed together. eg. -4 + -5 = -9 -4 x -5 = 20 It is easier to work with if you have no …negatives on the second number. You can switch the two symbols that are next to each other without disturbing the equation. For example: -4 + -5= -4 - 5= -9 It makes it easier to trace on a number line. I hope this helps more than confuses
A positive number minus a negative number? x - -x is the same as x + x because the negative signs cancel each other out and become positive. So, when you see two ne…gative signs right after the other, just add.
2 - -9 = 2 + 9 = 11
The question isn't too clear, but I'll assume it means, "what is a negative number minus a positive number?" The answer to that is: a negative number. To explain why, imagin…e the number line. A negative number is to the left of 0. Subtraction says to go reverse the direction you would if you were adding the number. Adding a positive number would mean you're going to the right. So you just go farther to the left. Wherever you are, you're still on the left side of the 0, so the result is a negative number.
The negative of a negative number is a positive number. The reason for this is that the first negative is a place holder for -1. When you have - - 4, that translates into -1 x… -4. When you multiply two negative numbers, you get a positive. For example: - - 7 = -1 x -7 = 7 - - r = -1 x -r = r
Solve one of the formulas for A, then substitute that into the other formula to solve for B, then substitute the solution for B into one of the formulas to solve for A. Here… is how: Givens: A+B=8 A-B=9 So: If A+B=8 then A=8-B Next, substitute this into the other formula... A-B=9 (8-B)-B=9 (-B) - B = 1 (-2B) = 1 B= (- 1/2) Next, substitute the solution for B into one of the formulas to solve for A.... A+B=8 A+ (-1/2) = 8 A = 8 and 1/2 So... B= (- 1/2) A = 8 and 1/2
9 - -3 = 9 + 3 = 12 12 - 8 = 4 9 - -3 - 8 = 4
Depends what you mean by "and". If they're added: never If they're subtracted: sometimes If they're multiplied or divided: always
You are taking something away a negative amount of times. Which means you are actually giving.
Answer is 43.4444
When you are doing maths, you must see the equations as numbers. So 5-1 consists from the numbers +5 and -1. So 5-1=-1+5 however if you substract with a negative number you a…ctually substract With -1 So 5--1, becomes 5+1. See it as I have a bucket of -ses and +ses. When I remove one - the sum of +ses is greater than the sum of the -ses
yes its true because of multiplication property, for eg: (-2)(-3)=6. here -x-=+. likewise +x- or -x+ =(-). and if take another eg like (-1)^2(-1 ka whole square )= +1.
Your question does not make sense. It would probably be interpreted as a + = ++a ---a
