Answer:
760772
Step-by-step explanation:
Given that the population of city Z was 420,000 in the year 2000.
The population is projected to grow at a constant rate of 2 percent per year,
We have to find the closest to the projected population of city Z in the year 2030
Since growing at 2% per year treating 2000 as year 0 we can say
where t is the no of years lapsed after 2000.
So at the year 2030, t = 30
Population at th eyear 2030
=
the projected population of city Z in the year 2030 is 760772
For this kind of problem is nneded to replace a letter b by a numerical value. Thne find the missing variable x .
then replace b = 5 in equality
4(5x - 3) = 8 ( x-2)
now eliminate parenthesis, by PEMDAS method
4•5x - 3•4 = 8x - 8•2
20 x - 12 = 8x - 16
now reorganize letters and numerical values
20x - 8x = -16 + 12
12x = -4
then finally x= -4/12 = -1/3
Answer: 60miles/hours
Step-by-step explanation:
From the question, a bus travels the 240 miles from Boston to New York and the bus departs at 11:00 a.m. and arrives in New York at 3:00 p.m. The time taken by the bus is (3:00pm - 11:00am) = 4 hours.
Average speed = Distance/Time
Average speed =240miles/4 hours
Average speed= 60miles/hours
The the average speed of this bus is 60miles/hour.
5w + 8 - w = 6w - 2(w - 4)
Hope this helps :)
