Well,
2.5(18) = 45
45 = 45
It's as simple as that. n=18 is the solution to the problem.
Answer:
-5/-2 or 2.5
Step-by-step explanation:
Because you gave two points that I'm guessing are from the graph I think that's the answer. Because when you use the slope formula y2-y1 over x2 - x1 you get -5/-2 or you either get 2.5 meaning that is the slope specifically saying the rate of change. You get 2.5 when you divide -5/-2 incase you need a decimal or want to simplfy it.
1 kilogram= 1,000 grams
2 kilograms= 2,000 grams
1,000/2=500
2,000+500=2,500 grams
2.5 kilograms= 2,500 grams.
Hope this helps!! :)
