Step-by-step explanation:
AED and DEB would add up to 180, the same goes for AEC and CEB
2/5 of 50 is 20. 50-20=30. Making FG=30
Answer: 34.2
For everyone 1 kilometer=.621371 so if you times that by 55 you get 34.1754 which rounds to 34.2
Answer:
1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)
2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal
3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.
I think it is D. not sure tho
