Answer 1

Answer:

Types of Inertia

In inertia, there isn't just one type. ... Inertia of motion - An object will continue at the same speed until a force acts on it. (i.e. Body going forward when a car stops.) Inertia of direction - An object will stay moving in the same direction unless a force acts on it.

Answer 2

Answer:

Let c represent the number of children (@ $1.75 each) and a represent the number of adults (@ $2.00 each).

We know that there were 379 people total, so c + a = 379. This implies that a = 379 - c

We also know that $1.75 c + $2.00 a = $609.25

By substituting a with 379 -c we have $1.75 c + $2.00 (379 -c) = $693.25

Use the distributive property to obtain $1.75 c + $693.25 - $2.00 c = $693.

Subtract $693 from both sides and combine like terms .

693-1.75= $691.25

693-2.00= $691
