How do you subtract an integer from another integer without using a number line or counters? Give an example.

Answers

Answer 1

Answer: The General rule for adding and subtracting numbers
1. Two integers with the same signs
Once 2 integers has the same sign, then just add the numbers.
For example
1. 1+1 = 2
2. 2 + 5 = 7

2. Two integers with different signs
When 2 integers has different sign, then find the difference
For example
1. 1-1 =0
2. 2 – 5 = -3

3. Two integers that vary in sign
When 2 integers vary in sign, then it will depend who which number carries the largest value
For example
1.   -3 + 2 = -1
2.   2 – 1 = 1

Answer 2

Answer:

Step-by-step explanation:

Additive inverse is the opposite of a number; the sum of additive inverses is zero. An integer and its additive inverse make up a zero pair.

example: 3

integer: -3+3=0

additive inverse: 3-3=0

Neil has a total of twelve $5 and $10 bills in his wallet. He has 5 times as many $10 bills as $5 dollar bills. How many of each does he have?

Answers

There are two $5 bills and ten $10 bills in Neil's wallet and this can be determined by forming the linear equation in two variables.

Given :

Neil has a total of twelve $5 and $10 bills in his wallet.
Neil has 5 times as many $10 bills as $5 dollar bills.

Let the total number of $5 bills be 'a' and the total number of $10 bills be 'b'. Then the total number of bills will be:

$a+b = 12$ --- (1)

It is given that Neil has 5 times as many $10 bills as $5 dollar bills, that is:

$5a = b$ ---- (2)

Now, substitute the value of 'b' in equation (1).

a + 5a = 12

6a = 12

a = 2

Now, put the value of 'a' in equation (2).

$5* 2 = b$

b = 10

There are two $5 bills and ten $10 bills in Neil's wallet.

2 5 dollar bills
10 10 dollar bills

ammount of 5 dollar bills= x
amount of 10 dollar bills = y
5x=y
x+y=12

x+5x=12

6x=12

x=2

12-x=y

12-2=y

10=y
