What is -2(4g-3)=30 I can't figure it out so I need so help

timofeeve [1]

Answer:

$g = - 3$

Step-by-step explanation:

$- 2(4g - 3) = 30$

$- 8g + 6 = 30$

$- 8g + 6 - 6 = 30 - 6$

$- 8g = 24$

$\frac{ - 8g}{ - 8} = \frac{24}{ - 8}$

$g = - 3$

The speedometer in Kevin's car reads in both miles/hour and kilometers/hour. What information is needed to convert between these

Akimi4 [234]

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<u> it is enough to know how many miles are in one kilometer.</u>

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.
