number am I?

Answer:

**Answer:**

- 865

**Step-by-step explanation:**

Let the 3-digit number is __abc__ = 100a + 10b + c.

__We have:__

- 100a + 10b + c - 100c - 10b - a = 297
- b = a - 6
- a = 2c - 2

__Simplify the first equation:__

- 99a - 99c = 297
- a - c = 3
- a = c + 3

__Solve for c by substitution:__

- 2c - 2 = c + 3
- 2c - c = 3 + 2
- c = 5

__Find a:__

- a = 3 + 5 = 8

__Find b:__

- b = 8 - 2 = 6

__The number is:__

(2) 3x⁴-4x³+7x-2 from 9-7x⁴+6x³-2x²-11x

**Answer:**

1) **5y + 5z**

2) **10x⁴ - 10x³ + 2x² + 18x - 11**

**Step-by-step explanation:**

Given the subtraction of the following polynomial expressions:

In order to make it easier for us to perform the required mathematical operations, we must first rearrange the terms in the ** subtrahend** by alphabetical order.

-3x - 4y + 11z

-3x - 9y + 6z ⇒ This is the __ subtrahend__.

Now, we can finally perform the subtraction on both trinomials:

In the *subtrahend*, the coefficients of x and y are both negative. Thus, performing the subtraction operations on these coefficients transforms their sign into positive.

**The difference is: 5y + 5z. **

Similar to the how we arranged the given trinomials in Question 1, we must rearrange the given polynomials in descending degree of terms before subtracting like terms.

**3x⁴- 4x³ + 7x - 2 ** ⇒ Already in descending order (degree).

9 - 7x⁴ + 6x³- 2x² - 11x ⇒ **-7x⁴ + 6x³- 2x² - 11x + 9**

In subtracting polynomials, we can only subtract __ like terms__, which are terms that have the same variables and exponents.

In the *minuend**, *I added the "**0x²**" to make it less-confusing for us to perform the subtraction operations.

The same rules apply in terms of coefficients with negative signs in the subtrahend, such as: -7x⁴, - 2x², and - 11x ⇒ their coefficients turn into positive when performing subtraction.

**Therefore, the difference is: 10x⁴ - 10x³ + 2x² + 18x - 11.**

a. Calculate the contribution to profit from the special order.

**Answer:**

**The contribution to profit from the special order us $38,000.**

**Step-by-step explanation:**

Consider the provided information.

We need to calculate the contribution on to profit from the special order.

Wolff Construction Company, which operates outside Packer’s normal sales territory, asks Packer to pour 40 slabs for Wolff’s new development of homes. Packer has the capacity to build 300 slabs and is presently working on 250 of them. Wolff is willing to pay only $2,750 per slab.

Sale = 40 × $2,750 = $110,000

To find the profit subtract the materials and labor cost from sale amount.

Particulars Amount

Sale (40 × $2,750) $110,000

Less: Variable expense

Unit level materials (40× $1,200) $48,000

Unit level labor(40× $600) $24,000

Contribution margin $38,000

The overhead cost will not be considered while determine the contribution to profit from accepting the order of 40 slab.

**Hence, the contribution to profit from the special order us $38,000.**

An **expression **is defined as a set of **numbers**, variables, and **mathematical operations. **The **value **of **−b²−2bx²−x** when the **value **of x=-2 is **−b²−8b + 4.**

In mathematics, an **expression **is defined as a set of **numbers**, variables, and **mathematical operations **formed **according **to rules **dependent **on the context.

The **value **of the **expression **−b²−2bx²−x will be,

−b² − 2bx² − x

= − b² − 2b(-2)² − (-2)

= − b² − 8b + 4

Hence, the **value **of **−b²−2bx²−x** when the **value **of x=-2 is **−b²−8b + 4.**

now divid 24 by 4

and u have 6

**Answer:**

4.5

**Step-by-step explanation: you divide 24 by what you do to get 6 which is 4 then you use 4 to divide 18 which is 4.5 or 4 and a half. Have A Great Day!**
