So for CE, you add CD and DE together = CE.
4x+8+27=6x
4x+35=6x
4x-6x=-35
-2x=-35
x=17.5
Answer is the second one: CE=17.5
For ST, you just add SM and MT.
27+58=85
ST=85
The answer to the problem is 2300
Answer:
7/6 or 1 1/6
Step-by-step explanation: you multiply 2 into 1/3 and 1/4 and get 2/3 and 2/4. You add 2/3 and 2/4 using lowest common denominator and get 14/12. Simplify 14/12 and get 7/6 or 1 1/6
the volume is 2040 inches^3
In the given question, all the necessary information's are already provided. Using these information's it is easy to find the average speed of the car in miles per hour. It is given that the car covers 10 laps in 18 minutes and each lap is 3.6 miles in length.
Total distance covered by the car = (10 * 3.6) miles
= 36 miles
Now we have to convert the time from minutes to hours. So
18 minutes = 18/60 hours
= 3/10 hours
Now we can easily calculate the average speed of the favorite car of Mathew.
Average Speed = 36 * (10/3) miles/hour
= 120 miles/ hour
