Emory used these steps to solve the equation. x + 7 = 3x + (−5).

1. Add 1 negative x-tile to both sides and create zero pairs.

2. Add 7 negative unit tiles to both sides and create zero pairs.

3. Divide the 12 negative unit tiles evenly among the 2 x-tiles.

4. The solution is x = −6.

the correct is answer is a 9-sided polygon!

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶

83-45=38

38 was the other number
