5w + 8 - w = 6w - 2(w -4).

Let's reduce the equation on the left:

4w + 8; (1)

and now let's reduce the equation on the right

6w - 2w +8 = 4w +8 (2).

We notice that (1) ≈ (2), and this is the only IDENTITY

Dory lives 2.5 miles from school. Jim lives 3.2 kilometers from school. Ely lives 2300 meters from school, and Chris lives 3000

dezoksy [38]

Answer: $Ely, Chris, Jim, Dory$

Step-by-step explanation:

The distances must be expressed in the same uni.

Let's express the distance in meters.

We know that Dory lives 2.5 miles from school.

Since:

$1\ mi = 1.61\ km$

The distance in kilometers is:

$(2.5\ mi)(\frac{1.61\ km}{1\ mi})=4.025\ km$

Since $1\ km = 1,000\ m$

The distance in meters is:

$(4.025\ km)(\frac{1,000\ m}{1\ km})=4,025\ m$

Jim lives 3.2 kilometers from school. The distance in meters is:

$(3.2\ km)(\frac{1,000\ m}{1\ km})=3,200\ m$

Chris lives 3,000 yards from school.

Since:

$1\ m = 1.09\ yd$

The distance in meters is:

$(3,000\ yd)(\frac{1\ m}{1.09\ yd})=2,752.29\ m$

Therefore, the order of the students from closest to farthest from school is:

$Ely, Chris, Jim, Dory$
