Step-by-step explanation:
22+24+26+28+30+32+34+36+38+40+42+44= 396
To simplify, you must distribute the 2 into the 5x and -4 by multiplying 2 with 5x and 2 with -4.
<span>2(5x – 4) + 3x
2 x 5x = 10x
2 x -4 = -8
You will get 10x - 8 + 3x
Now you must combine like terms or add like terms. In this case we must add 10x and 3x
10x + 3x = 13x
Finally the answer would be 13x - 8</span>
Answer:
That would be 14 miles ÷ 6 hours which would be 2.3333 or 2 and 1/3
The correct answer is 3: 35
Explanation:
To calculate at what time Jenny will arrive in Rochefort, the first step is to calculate the approximate time of the trip. Now, to calculate this consider the time of a movement (t) equals to the distance (d) divided by the speed (s), the process is shown below:
t = 483 km / 84 km/h
t = 5.75 hours
In this number 5 refers to the hours and 0.75 represents 45 minutes considering 0.75 x 60 minutes in one hour = 45 minutes. Therefore, the total time from Paris to Rochefort is 5 hours and 45 minutes. Now, to calculate the time of arrival add this result to the time of departure.
Add the hours: 5 hours + 9 hours: 14 hours
Add the minutes: 50 minutes + 45 minutes =95 minutes
95 minutes are equivalent to 1 hour (60) minutes and 35 minutes
Calculate the total
Hours: 14 hours + 1 hour = 15 hours or 3 in the 12 hour system (15 hours - 12 hours = 3 p.m.)
Minutes: 35 minutes
