Answer:
y=120-4x
Step-by-step explanation:
Here we are given the average speed for Day 1 and Day 2 and the time of ride . We asked to Find an expression to determine the total distance travelled in two days.
Day 1 :
Avg Speed = 8 mph
Let the time for travelling = x hrs
Hence Distace Travelled D1= Speed x Time
D1=8x
Day 2 :
Avg Speed = 12 mph
Total time of travelling for two days is given as 10 hours . Hence the time of travelling for day 2 is
= (10-x) hrs
Hence Distance travelled in Day 2 D2 = speed x time
D2 = 12(10-x)
D2=120-12x
Total Distance travelled = D1 + D2
= 8x+120-12x
=120-4x
If the total distance travelled is denoted by y
The expression will be
y=120-4x
Answer:
17.
Step-by-step explanation:
6^2 - 19
= 36 - 19
= 17.
Answer:
The result will be: 5x³ -11x² -9x + 18
They practiced 35 minutes longer on the second day.
Answer:
c. 35/12
Step-by-step explanation:
Use soh cah toa, tangent equals opposite over adjecent. A also remember tangent by remembering that it is the only ratio to not use the hypotenuse.
