andrey2020 [161]

Answer:

W, M, A and G

Step-by-step explanation:

The question is not correct, the correct question is Adams, Greensburg, Middletown, and Waldron are four towns in Indiana on a nearly straight highway. If the highway is represented by a line, the  towns can be represented by four points: A, G, M, and W. Given that MG + WM = WG and MA = MG - AG determine the  proper order of the four towns.

Answer: The line segment addition postulate states that for a line segment AC with point B which lines on AC, then this equation holds:

AB + BC = BC

Given that MG + WM = WG, this means that point M lies between the segment WG.

Also, MA = MG - AG

MA + AG = MG, hence point A lies between segment MG

Therefore the order of the points is W, M, A and G

(m-3)/(7)=(m)/(m+8) Solve the proportion.
ExtremeBDS [4]

Answer: m=6, m=-4

Step-by-step explanation:

To solve this proportion, we have to cross multiply.

\frac{m-3}{7} =\frac{m}{m+8}

(m-3)(m+8)=7m

Now that we have cross multiplied, we actually need to FOIL the left side to expand the equation.

m^2+8m-3m-24=7m

Combine like terms.

m^2+5m-24=7m

We can move all terms to one side and then solve for m.

m^2-2m-24=0

We can actually factor this to:

(m-6)(m+4)=0

We set each factor equal to 0 to find m.

m-6=0

m=6

m+4=0

m=-4

"After 64 seconds, ABOUT HALF of the brands of milk chocolate are LIKELY  to melt and NONE of the brands of Dark Chocolate are likely to melt"

Step-by-step explanation:

The right answer is

"After 64 seconds, ABOUT HALF of the brands of milk chocolate are LIKELY  to melt and NONE of the brands of Dark Chocolate are likely to melt"

We can easily check this solution by seeing the time it took for each chocolate to melt in the attached picture.

After 64 seconds have passed, half of the brands of milk chocolate had already melted, but the dark chocolate time starts after 200s

Elanso [62]

We can divide the amount he traveled (640) by the time he traveled (10):

640 / 10 = 64.

So Curtis drove 64 miles per hour.

Check:

64 miles per hour multiplied by 10 hours:

64 * 10 = 640
