Answer:
Step-by-step explanation:
We have been given that Camacho is buying a monster truck. The price of the truck is x dollars, and he also has to pay a 13% monster truck tax. We are asked to find the total amount paid by Camacho for the monster truck.
The total cost of monster truck would be x plus 13% of x.
Therefore, Camacho paid dollars in total for the truck.
Answer: you travelled 10 km
Step-by-step explanation:
Pam jogged up the hill at 6 km/h.
Let x represent the number of kilometers that you travelled by jogging up the hill or returning back.
Time = Distance/speed
Pam jogged up the hill at 6 km/h.
Time spent in jogging up the hill would be
x /6
She then jog back down the hill at 10 km an hour. Time spent in jogging down the hill would be
x /10
If the total jogging tie is 1 hour 20 minutes, converting to hours, it becomes 1 + 20/60 = 1.33
Therefore
x /6 + x/10 = 1.33
10x + 6x = 80
16x = 80
x = 80/16 = 5
Total distance travelled up and down the hill would b
5 × 2 = 10 km
Answer:
just look for the LCM of 6,8,12,9 then that will be your answer
