Answer 1

Solving the equation: IIxI - 2I = 6

To solve the equation IIxI - 2I = 6, we need to simplify the expression and find the value of x.

First, let's simplify the expression IIxI - 2I. The notation IIxI represents the absolute value of x.

The absolute value of a number is its distance from zero on the number line. So, IIxI is equal to x if x is positive

Answer 2

Solving the Equation: IIxI - 2I = 6

To solve the equation IIxI - 2I = 6, we need to simplify the expression and find the value of x.

Let's break down the equation step by step:

1. IIxI represents the absolute value of x. So, IIxI can be simplified as follows: - If x is positive or zero, IIxI is equal to x. - If x is negative, IIxI is equal to -x.

2. 2I represents twice the absolute value of I. So, 2I can be simplified as follows: - If I is positive or zero, 2I is equal to 2I. - If I is negative, 2I is equal to -2I.

Now, let's substitute these simplified expressions back into the equation:

- If x is positive or zero, the equation becomes x - 2I = 6. - If x is negative, the equation becomes -x - 2I = 6.

Since we don't have any information about the value of I, we cannot simplify the equation further without additional context.

Simplifying and Finding the Value: 6.36 + a + (-2.9) + (-4.36) + 2.9

To simplify the expression 6.36 + a + (-2.9) + (-4.36) + 2.9, we can combine like terms:

6.36 + a + (-2.9) + (-4.36) + 2.9 = (6.36 - 2.9 - 4.36) + (a + 2.9)

Simplifying the numbers within the parentheses:

6.36 - 2.9 - 4.36 = -0.9

Now, the expression becomes:

-0.9 + (a + 2.9)

To simplify further, we can combine the terms:

-0.9 + (a + 2.9) = a + 2

Therefore, the simplified expression is a + 2.

Number of Integers between -7 and 5 on the Number Line and Their Sum

To find the number of integers between -7 and 5 on the number line, we need to count the integers within this range, excluding the endpoints.

The integers between -7 and 5 are: -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4.

There are a total of 11 integers between -7 and 5.

To find the sum of these integers, we can add them up:

-6 + (-5) + (-4) + (-3) + (-2) + (-1) + 0 + 1 + 2 + 3 + 4 = -15

Therefore, the sum of the integers between -7 and 5 is -15.

I hope this helps! Let me know if you have any further questions.
