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

Pipe A filled for 3 days and pipe B filled for 2 days
Both can fill: 1/3 + 1/2 = 2/6 + 3/6 = 5/6
Answer: 5/6 of a day to fill the pool
Answer:
Below.
Step-by-step explanation:
As both the right sides of the 2 equations are equal to y, by the transitive law of equality 3x + 1 = -2x + 3.
W then solve this equation for x then substitute this value of x in the first equation ( y = 3x + 1) to find the value of y.

Step-by-step explanation:
This sounds like a Pythagoras theorem question. So what I would do is 18^2 - 10^2= Ans
Then square root the answer
