Answer: The slope of two parallel lines are same. Since one pair of opposite sides are equal and parallel, therefore the another set of opposite sides is also parallel and equal. The opposite sides are prallel and equation, so the quadrilateral PQRS is a parallelogram.

C = k - 273.15 (a) Write two other related equations . (b) If the temperature is 23 in degrees Celsius , what is the temperature
Alona [7]

Answer:

(a) k = C + 273.15, F = 1.8(k - 273.15) + 32

(b) k = 296.15

(c) 25 celcius is greater than 300 kelvis.

Step-by-step explanation:

(a) one equation would be to solve for k instead of c, and another related equation could be from kelvin to Farenheit.

C = k - 273.15

C + 273.15 = k

k = C + 273.15

F = 1.8(k - 273.15) + 32

(b) for this one you have to substitute in the previous equation and solve for k.

23 = k - 273.15

k = 23 + 273.15

k = 296.15

(c) you have to convert either kelvins to celcius or celcius to kelvins.

C = k - 273.15

C = 300 - 273.15

C = 26.85

So 25 celcius is greater than 300 kelvis.

What is a correct method of solving the equation x/3-6=9 for x? please help thx
stira [4]

Answer:

45

Step-by-step explanation:

\frac{x}{3} -6=9

add 6 on both sides to eliminate it(doing this will get us closer to the variable)

x/3=15

multiply both sides by 3

x=45

hope this helps!

9. What's the least common multiple (LCM) of 2, 6, and 8?
algol [13]

Answer:

24

Step-by-step explanation:

The LCM or least common multiple of these numbers is 24

To get 24, you list all the multiple of these numbers until they all share at least one

So

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, <u>24</u>

6, 12, 18, <u>24</u>

8, 16, <u>24</u>

They all share 24 so this is the LCM

Hope this helps
