Answer:
9 Signs
Step-by-step explanation:
The hiking trail is 4 kilometer long.
Signs are placed at the beginning and at the end of the trail.
4km = 4000m
We can solve this using simple arithmetic progression.
- The first term,a= 0
- The common difference,d= 500.
- The last term,l= 4000.
Therefore:
Last term, l=a+(n-1)d
4000=0+500(n-1)
4000=500n-500
4000+500=500n
4500=500n
Divide both sides by 500
n=9
Therefore, there are a total of 9 signs on the entire trail.
CHECK
The signs are placed at this marks
0m,500m,1000m,1500m,2000m,2500m,3000m,3500m and 4000m
Answer:3
Step-by-step explanation: 3(3)-4 =5
Area now is 5•5 equivalent to 25 :)
4/12 equals 2/6 which is smaller than 4/6 so the correct answer is 4/12 <4/6
Answer:
You can multiply the 2nd equation by either -3 or -6
Step-by-step explanation:
If you are using elimination (imo substitution on this problem would be easier), then you need to eliminate <em>one </em>of the variables. If you are wanting to eliminate x first, then multiply by -3. If you want to eliminate y first, then multiply by -6.
Answer:
C
Step-by-step explanation:
slope intercept is y=mx+b
The y-intercept is at 2 so b=2.
The slope is rise/run, equaling -3
so y= -3x+2
