ANSWER
EXPLANATION
Let the number of people riding in each bus be x.
We have that 20 people are riding in 4 vans and there are x people in each van <em>(given that there is an equal number of people in each van)</em>.
This means that the product of the number of people in each van and the number of vans must be equal to the total number of people.
That is:
Solve for x:
That is the answer.
Answer:
Ariel will be at an elevation of -3 meters.
Step-by-step explanation:
We have been given that Eric is swimming along the surface of the sea. He uses positive numbers to represent elevations above the surface of the sea and negative numbers to represent depths under the surface of the sea.
Since Eric is swimming along the surface of the sea, so his elevation will be 0.
As we are told that Mark is sitting above Eric and Eric uses positive number for elevation above surface of the sea, so Mark's elevation will be positive.
As we are told that Ariel is diving below Eric and Eric uses negative number for elevation below surface of the sea, so Ariel's elevation will be negative.
Therefore, Ariel will be at an elevation of -3 meters.
