How to subtract:

1.Subtracting Larger Whole Numbers by Borrowing

2. Write the smaller number directly below it. Make sure that you line up the tens and ones columns, so that the 3 in "32" is directly above the 1 in "17" and that the 2 in "32" is directly above the "7" in 17.

3. Subtract the number in the ones column of the bottom number from the number in the ones column of the top number. Now, this can get a little bit tricky when the bottom number is larger than the top number. In this case, 7 is larger than 2. Here's what you need to do:[1]

You'll need to "borrow" from the 3 in "32" (also known as regrouping), in order to turn that 2 into a 12.

Cross off the 3 in "32" and make it a 2, while making the 2 a 12.

Now, you have 12 - 7, which is equal to 5. Write a 5 below the two numbers you subtracted, so it lines up with the ones column in a new row.

4. Subtract the number in the tens column of the bottom number from the number in the tens column of the top number. Remember that your 3 is now a 2. Now, subtract the 1 in 17 from the 2 above it to get (2-1) 1. Write 1 below the numbers in the tens columns, to the left of the 5 in the ones column of the answer. You should have written 15. This means that 32 - 17 = 15.

5.Check your work. If you want to be sure that you correctly subtracted the two numbers, then all you have to do is to add the answer to the smaller number to make sure that you get the larger number. In this case, you should add your answer, 15, to the smaller number in the subtraction number, 17. 15 + 17 = 32, so you've done your work correctly. Well done!

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
