In order to make 1 bike it requires 1 horn, 2 tires, and 1 chain. What would be the coefficients for the horn, tire, and chain,

cestrela7 [59]

Bike is B
Horn is H
Tire is T
Chain is C

one bike would be B = H + 2T + C
you would have to multiply both sides by 4 to make 4 bikes, so then it would be
4B = 4H + 8T + 4C

Sever21 [200]

Answer : The correct option is, $-89.2^oF\text{ and }183.9K$

Explanation :

The conversion used for the temperature from Fahrenheit to degree Celsius is:

$^oC=(^oF-32)\times \frac{5}{9}$

where,

$^oF$ = temperature in Fahrenheit

$^oC$ = temperature in centigrade

The conversion used for the temperature from degree Celsius to Kelvin is:

$K=273.15+^oC$

where,

$K$ = temperature in Kelvin

$^oC$ = temperature in centigrade

As we are given the temperature in Fahrenheit is, -10

Now we have to determine the temperature in degree Celsius.

$^oC=(^oF-32)\times \frac{5}{9}$

$^oC=(-128.6^oF-32)\times \frac{5}{9}$

$^oC=-89.2$

Now we have to determine the temperature in Kelvin.

$K=273.15+^oC$

$K=273.15+(-89.2^oC)$

$K=183.9$

Therefore, the temperature in degree Celsius and Kelvin are, $-89.2^oF\text{ and }183.9K$
