Answer:
the solution is given by s=9 because it makes the value of 3s+12 equal to 21
Step-by-step explanation:
1 split into two equal parts so the answer is 2
You need to use the slop formula (y2-y1/x2-x1)
9 -3/5--3
6/5+3
6/8
3/4
The slope is 3/4
Answer:
Taylor is 14.
Step-by-step explanation:
Max is 3. Emma is six years older than Max.
3+6=9
Emma is 9. Taylor is five years older than Emma.
9+5=14
Answer:
Average speed =
miles per hour
Step-by-step explanation:
Formula to calculate the average speed of an object is,
Average speed = 
If I travel with the speed of x mph for t hours,
Total distance covered = Speed × Time
=
=
miles
Similarly, if I travel with the speed y mph for t hours,
Total distance covered =
miles
Total distance covered by me =
miles
Total time taken to cover this distance = 
=
hours
Therefore, expression for the average speed will be,
Average speed = 
= 
=
miles per hour
