<h2>Answer: x = 6</h2>

* = things that have changed or are being changed

<h2>Explanation:</h2>

1. rearrange terms

*4 4  +  3 *  =  5  +  2  +  2 0

*3x + 44* = 5x + 2 + 20

2. combine like terms

3 + 44 = *5x + 2* + 20

3 + 44 = *7x* + 20

3. Subtract  4 4  from both sides of the equation

3x + 44 = 7x + 20

3x + 44 *-44* = 7x + 20 *-44*

4. Simplify

(Subtract the numbers)

3x + *44 - 44* = 7x + 20 - 44

3x = 7x + 20 - 44

(Again)

3x = 7x + 20 *- 44*

3x = 7x - 24

5. Subtract  7  from both sides of the equation

3x = 7x - 24

3x *- 7x* = 7x - 24 *- 7x*

6.  Combine like terms

*3x - 7x* = 7x - 24 - 7x

*-4x* = 7x - 24 - 7x

(Again)

-4x = *7x* - 24 *- 7x*

-4x = - 24

7. Divide both sides of the equation by the same term

-4x = - 24

\frac{-4x}{*-4*} = \frac{-24}{*-4*}

8. Simplify

(Cancel terms that are in both the numerator and denominator)

* \frac{-4x}{-4} * = \frac{-24}{-4}

*x* = \frac{-24}{-4}

(Divide the numbers)

x = \frac{-24}{-4}

x = 6

Help with 35 to 40, don’t know if I am right
Sedaia [141]

Step-by-step explanation:

35. 1000 m / 1 km = 10³

Move the decimal point 3 places to the right.

36. 100 cm / 1 m = 10²

Move the decimal point 2 places to the right.

37. 1 mm / 1000 μm = 10⁻³

Move the decimal point 3 places to the left.

38. 1 km / 1000 m × 1 m / 100 cm = 10⁻⁵

Move the decimal point 5 places to the left.

39. 1 Mm / 10⁶ m × 1 m / 10⁶ μm = 10⁻¹²

Move the decimal point 12 places to the left.

40. 100 cm / m × 1000 m / km = 10⁵

Move the decimal point 5 places to the right.
