1 answer:

6 0

First, isolate . To do so, divide both sides by .Then, eliminate the radical. So, square both sides of the equation To have h^2 only at the right side, subtract both sides by r^2.And, to have h only, take the square root of both sides of equation

5 The cost of an adult's ticket into a theme park is $a.

natta225 [31]

Answer:

<u>Total Cost (in dollars) = a + c</u>

Step-by-step explanation:

<u>Algebra</u>

When mathematics quantities are generalized into letters or variables, then we are dealing with algebra.

We are said the cost of an adult's ticket into a theme park is $a and a child's ticket costs $c. Since both quantities are unknown, we must treat them as variables and use the same logic procedure to solve the problem as if they were numbers.

The total cost for an adult and a child is the sum of both individual costs, thus

Total Cost (in dollars) = a + c
