Answer:
4020 grams
Step-by-step explanation:
4kg=4000g
2 dag= 20g
Total: 4000g + 20g = 4020g
Keeping in mind that, there are 3.78 liters in 1 US gallon and say 30days per month and 24 hours in a day.. then
If one addend is negative, you basically subtract it from the other number
-13 + 13 basically equals 13 - 13 =0
Divide .30 (30%) with 60
60/.30 = 200
200 is your answer
hope this helps
