Answer:
After adding 8 you get 14 = x/4.
Step-by-step explanation:
6=x/4-8 Add 8 to both sides:
6 + 8 = x/4 - 8 + 8
14 = x/4
x = 4*14
x = 56.
11,513 is the answer I really don't know how to write it all out sorry
If you use the slope formula, the answer is m = 2
Answer:
54
Step-by-step explanation:
Angles in a triangle add to 180° and we can see a right angle so
x = 180 - ( 90 + 36 )
x = 180 - 126
x = 54
We must look at this question in steps
The first half of the journey is travelled at 40 km/h
Half of 100km is 50 km
Using the formula
Distance = Speed x Time
Speed = Distance / Time
Time = Distance / Speed
We can work out the time:
50km / 40km/h = 1.25 hours
Next we look at the second half of the journey
50km at 80km/h
50km / 80km/h = 0.625 hours
Add together both times to work out how long the entire journey took
1.25 + 0.625 = 1.875 hours
Using the Speed formula from before
Speed = 100km / 1.875 =
53 1/3 km/h or 53.3 recurring km/h
