Answer:
- 170 km on the ground
- 15 km over water
Step-by-step explanation:
Let t represent the amount of time spent over level ground. Then 5.75-t is the time spent over water. The total distance covered is ...
distance = speed · time
40(t) + 10(5.75 -t) = 185
30t + 57.5 = 185
30t = 127.5
t = 4.25
40t = 170
185 -170 = 15
The hovercraft covered 170 km on the ground and 15 km on the water.
Answer:
5y
Step-by-step explanation:
First find all the factors of 15y^3 and then all the factors of -20y
15y^3 = 3 , 5 , y, y, y
-20y = 2 , 4, 5, 10, y
The GCF is 5 and y. We choose 5 because it is the greatest number and common in both sets. We also choose one y because it is common in both sets and one y is the greatest common y.
Answer = 5y
You can also do this by using the prime factorization method.
