Answer:
Step-by-step explanation:
4k + 6k=10k
5 * 10=50
180-50 (Think so : ) .)
10k = 130
k=130/10
=13

Answer:
7r+63
Step-by-step explanation:
7(r+9)
7(r)+7(9)
7r+63
Hope this helps .-.
So this is not too hard, as with any math problem we write what we know.
Starting speed: 80km/h
Time from P to Q: 2.5h
Increase in speed: 20km/h (25% is dividing by 4)
Distance from Q to R: 150 kilometers
So let's find the speed and distance for both legs of the trip.
Speed for P to Q: 80km/h
Distance from PtoQ: 200km (2.5h * 80km/h)
Speed from Q to R: 100km/h (80 +20)
Distance from QtoR: 150km.
Now we multiply the speeds by their respective distances add them and then divide by the total distance.
((80 *200) + (100 * 150))/350 = ~88.57143
Answer:
I personally think it is b. because there are only two choices, true or false. The answers are for 4 questions so,
