Assuming you typed this correctly, and how you wanted it, then the answer(s) would be x=3, or x=8. Both answers are correct. If it were multiple choice, then the answer would look something like: X=3 or 8.
If you meant 2x, then the answer would be x=8/3. This is a fraction
Answer:
l:9
p:16.4
Step-by-step explanation:
l x w = A
A÷w=l
37.8÷4.4=9
2l+2w=P
18+8.4=16.4
I'm not sure if that's what you mean, but I assume you might want to know how long did it take to make one lap if someone did 21 laps in 7 minutes.
If so, just divide 7 by 21:
7 ÷ 21 = 0.3333333... (repeating decimal) or 1/3 as a fraction.
It means that one lap took 1/3 of a minute (20 seconds).
If that's not what you meant, please specify the question :)
Answer:
Step-by-step explanation:
Given
Required
Determine the distance (y) covered by his car
First, we calculate the distance walked.
This is calculated as follows;
This means that he walked 4.5 km
The total distance can be expressed as a sum of distance covered while walking and distance covered by car.
i.e.
Make Car the subject
This gives
<em>Hence, his car travelled 15.5km</em>
