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

Answers

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

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

Hope this helps!

How many solutions exist for the given equation? 3(x – 2) = 22 – x zero one two infinitely many

Answers

An equation can either have a solution, no solution or infinite many solutions

The equation has one solution.

The equation is given as:

$\mathbf{3(x - 2) = 22 - x}$

Open bracket

$\mathbf{3x - 6 = 22 - x}$

Collect like terms

$\mathbf{3x + x = 6 + 22}$

Evaluate like terms

$\mathbf{4x = 28}$

Divide both sided by 4

$\mathbf{x = 7}$

The above equation is true for x = 7

This means that: the equation has one solution.

Answer:

one solution

Step-by-step explanation:

Given

3(x - 2) = 22 - x ← distribute parenthesis on left side

3x - 6 = 22 - x ( add x to both sides )

4x - 6 = 22 ( add 6 to both sides )

4x = 28 ( divide both sides by 4 )

x = 7

Find two consecutive numbers whose squares differ by 25

Answers

Consecutive numbers means that they are one after the other (i.e. 1, 2, 3 are consecutive numbers). The square of a number signifies the product of this number times itself (i.e. 2 times 2 = 4, so 4 is the square of 2). If these squares differ by 25, then when they are subtracted from one another, the difference will be 25:

12 x 12 = 144
13 x 13 = 169

169 - 144 = 25
