**Answer: 1.57 x 104**

**Step-by-step explanation: How to Convert a Number to Scientific Notation**

**The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.**

**Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.**

**Count how many places you moved the decimal point. This number is b.**

**If you moved the decimal to the left b is positive. **

**If you moved the decimal to the right b is negative. **

**If you did not need to move the decimal b = 0.**

**Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."**

**Remove trailing 0's only if they were originally to the left of the decimal point.**

Please help!!!

### Answers

**Answer:**

x=1

**Step-by-step explanation:**

subract 4.3 from both sides. add x to both sides. divide by 2.2 from both sides

The **solution** to the **equation** 1.2x + 4.3 = 2.1 - x is x = -1.

Given is an **equation** 1.2x + 4.3 = 2.1 - x, we need to **solve** for x,

To solve the **equation** 1.2x + 4.3 = 2.1 - x, we can follow these steps:

1. **Combine** like terms on both sides of the equation:

1.2x + x = 2.1 - 4.3

2. **Simplify** the equation:

2.2x = -2.2

3. **Divide** both sides of the equation by 2.2 to isolate x:

x = -2.2 / 2.2

4. **Simplify** the right side of the equation:

x = -1

Therefore, the **solution** to the **equation** 1.2x + 4.3 = 2.1 - x is x = -1.

The basketball gym at Dustin's school was built in the 1940s and needs a lot of repairs. So, the school is asking families for donations to build a new gym. Dustin convinced some local businesses to match a fraction of the families' donations. There is a proportional relationship between the amount of money a family donates (in dollars), x, and the matching contribution (in dollars) from local businesses, y. When a family donates $12, the businesses contribute $9. Write the equation for the relationship between x and y.

### Answers

**Answer:**

**The equation representing the relationship between x and y is that;**

**4y = 3x**

**Step-by-step explanation:**

**Here, we want to write a relationship.**

From the question, we are told that the amount donated by the family which is x dollars is proportional to what local businesses gave.

From the question, there was an example in which a family gave $12 and local businesses gave $9

So let us establish a relationship using ratio of x to y

Thus;

12/9 = x/y

12y = 9x

4y = 3x

Solve for x if 5x + 2(x - 3) = 7x - 6

Help me plsss

### Answers

**Answer:**

x = 3

**Step-by-step explanation:**

Step 1: Simplify both sides of the equation.

5x + 29 (x − 3) = 7x − 6

5x + (29) (x) + (29) (−3) = 7x + −6 (Distribute)

5x + 29x + −87 = 7x + −6

(5x + 29x) + (−87) = 7x − 6 (Combine Like Terms)

34x + −87 = 7x − 6

34x − 87 = 7x − 6

Step 2: Subtract 7x from both sides.

34x − 87 −7x = 7x −6 −7x

27x − 87 = −6

Step 3: Add 87 to both sides.

27x − 87 + 87 = −6 + 87

27x = 81

Step 4: Divide both sides by 27.

27x/27 = 81/27

x = 3

Which function represents the same relationship?

### Answers

**Answer:**

y=-3x-10.5

**Step-by-step explanation:**

Let's use the first set of numbers.

-7.5 and 12

-3.5 and 0

Our rise here is -12 and run is 4. So, our slope is -3.

Now we just need our intercept.

y = mx + b

y = -3x + b

0 = -3(3.5) + b

b = -10.5

The **function** represents the same **relationship** between x and y will be x + 3y + 3.5 = 0.

Sorry if the other answer misleads you. Here is the * real* answer!

The **answer** to the **expression **m +(3n - 5)² is 55.

What is Expression?

A **mathematical **operation such as subtraction, addition, multiplication, or division is used to **combine terms **into an **expression**. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a **constant**.**Variable**: A symbol without a set value is referred to as a variable.**Term**: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.**Coefficient**: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

m +(3n - 5)²

Now, put the **value **of m= 6 and n= 4 we get

m +(3n - 5)²

= 6 +(3(4) - 5)²

= 6 +(12 - 5)²

= 6 +(7)²

= 6+ 49

= 55

Hence, the **answer **is 55.
