Take apart the number to make a 10. Then subtract.

Mathematics

Licemer1 [7]3 years ago

Answer:

This is one of a variety of "subtraction solutions"--basically a different way to subtract by breaking numbers down into 10-digit chunks.  It's not especially helpful for small subtraction problems, but as math gets more complicated, this method will come in handy.

Step-by-step explanation:

Here's an example: Jim had a bag of 15 jelly beans.  He eats 8.  How many jelly beans does he have left?  <u>Take apart the number to make a 10. Then subtract.</u>

Here, you need to "take apart" the 8 to make your 15 jelly beans 10, then you subtract the remainder of 8 to get your solution.  In other words,

 --"take apart" 8 into 5 and 3 (because you're going to need a 5 to make 15 into 10).  15 minus 5 equals 10.  HOORAY!  You have your 10.  Now, subtract the remaining 3.  10 minus 3 equals 7.  Huzzah--your final answer!

On paper, the problem looks like this:

<u>15 - 8 (</u><u>5, 3</u><u>) = ?</u>

15 - 5 = 10

10 - 3 = 7

So...15 - 8 = 7

Answer:

  A)  5x+12 = -12x-12

  D)  5x+12 = -5x-12

Step-by-step explanation:

If you subtract the right side expression from both sides, you will get an equation with something equal to zero. If the 'something' has a variable in it, there is exactly one solution.

A: (5x+12) -(-12x-12) = 17x+24 = 0 . . . one solution

B: (5x+12) -(5x-5) = 17 = 0 . . . . no solutions

C: (5x+12)-(5x+12) = 0 = 0 . . . . infinite solutions

D: (5x+12) -(-5x-12) = 10x +24 = 0 . . . one solution

Answer:

  (x, y) → (-∞, -∞), (+∞, +∞)

Step-by-step explanation:

The expression is of odd degree with a positive leading coefficient. It will have a generally upward slope (/). That is, the sign of f(x) will match the sign of x for large-magnitude values of x:

  x → -∞, f(x) → -∞

  x → ∞, f(x) → ∞
