Answer:
12 ft
Step-by-step explanation:
You have a right triangle with the hypotenuse = 13 and one leg = 5
Let x = distance above the ground that the ladder touches the wall
Now use the Pythagorean theorem
It looks like none of the choices are correct, because the answer is 12 ft.
By the way, it is impossible for the ladder to reach up the wall a distance longer the the length of the ladder. Think about it. OK?
<em>An adult ticket costs $205 and a child ticket costs $49.</em>
<h2>Explanation:</h2>Hello! Recall you have to write complete questions in order to find exact answers. Here I'll assume the complete question as:
<em>Two families are planning a trip to Disney. The Smith family bought tickets for 2 adults and 3 children for $557. The Jones family bought tickets for 2 adults and 1 child </em><em>for $459</em><em>. How much does and adult and child ticket cost?</em>
To solve this problem, we need to write a system of linear equations in two variables. So, we know some facts:
Let:
For the Smith family:
Cost for the 2 adults:
Cost for the 3 children:
Total cost:
For the Jones family:
Cost for the 2 adults:
Cost for the 1 child:
Total cost:
So we have the following system of linear equations:
Subtracting (2) from (1):
Finally, <em>an adult ticket costs $205 and a child ticket costs $49.</em>
