Answer:
321.
Step-by-step explanation:
First, divide 2250 by 7 to see how many times 7 can go in. You should get 321 and 3 as your remainder. To put it into mixed number format, it would put 321 as your whole number and your remainder divided by 7. It would be 321 3/7. Hope this helps :)
If you want to check if (1,2) is a solution to the system, you have to plug the x and y values back into both equations. If they work for one equation, but not the other, than the coordinates are not a solution to the system.
3(1) - 4(2) = -5
3 - 8 = -5
-5 = -5
2 = 4(1) - 2
2 = 4 - 2
2 = 2
Since both of these checks are true, then (1,2) is a solution to the system.
I believe the answer is B. 39, 49, 59
26 - 12 = $14

1a.
you still have
k=C+273.15
k-C= 273.15 as related equations
b. at C=23
k=23+273.15 = 296.15
c. 25°C in kelvin = 25+273.15 = 298.15
so 300K is greater than 25°C
