Point M is the midpoint of segment AB. If AM = 50 – 3x and MB = –20 + 4x, find the value of x. x = -10 x = 10 x = -20 x = 20

1 answer:

4 0

(50-3x)-(-20+4x) = 0

50-3x+20-4x = 0

70-7x = 0

-7x = -70

7x = 70

x = 10

Answer:

a) the number of miles in 1 kilometer

Step-by-step explanation:

The car converts from miles/hour to kilometers/hour, if we see the time measurement (hours) it stays the same in both units.

So to make the conversion it is enough to know how many miles are in one kilometer.

For example, lets convert 10miles/hour to kilometers/hour.

there are 0.621371 miles in 1 kilometer, so if we divide 10miles/hour by 0.621371 we get kilometers/hour units:

$\frac{10miles}{hour} (\frac{1kilometer}{0.621371miles} )=16.0934\frac{kilometers}{hour}$

Thus to make the conversion between the two units is needed the number of miles in 1 kilometer.

$25x = 65$
Divide both sides by 25 to isolate x:

$\frac{25x}{25} = \frac{65}{25} \\ \\ x = \frac{13}{5} = 2.6$
