Answer:
ab=bc because b devide ac in two equal sizes
ac=ab+bc
ac=2×ab
ac =2×bc
lets substitute ac and bc there we are given
x+3=2(3x-1)
x+3=6x-2
-5x/-5=-5/-5
x=1
ab=3(1)-1
ab=2
4/3
40/30
60/45
Simply multiply or divide both the 20 and the 15 to get an equivalent ratio.
Answer:
16,080 km.
Step-by-step explanation:
We want the total number of kilometers in one year.
so
4 weeks /month.
for Work: 9 months in the year 60 km/day 5 days/week
Family Visit : 720 km for 4 times a year
Personal: 200 km / month
Work total = 60 km/day * 5 days/week * 4week/month * 9 months
WorkTotal= 60*5*4*9 = 10,800 km
FamilyTotal= 4*720 = 2880 km
Personal = 200*12 = 2400 km
Total = 10,800 + 2880 + 2400 = 16,080 km
