Answer:

x = 12

Step-by-step explanation:

In a right triangle (a triangle that has a ninety degree angle in it) the the square of the side opposite the right angle is always equal to the sum of the squares of the other two sides. Therefore, we can use the information we are given to figure out the missing side:

15^2=225\\9^2=81\\225-81=144\\\sqrt[2]{144}=12

Pam’s eye-level height is 324 ft above sea level, and Adam’s eye-level height is 400 ft above sea level. How much farther can Ad
Tanzania [10]

Answer: The answer is √6 mi.

The formula is: d = √(3h/2)

Pam:

h = 324 ft

d = √(3 * 324/2) = √486 = √(81 * 6) = √81 * √6 = 9√6 mi

Adam:

h = 400 ft

d = √(3 * 400/2) = √600 = √(100 * 6) = √100 * √6 = 10√6 mi

How much farther can Adam see to the horizon?

Adam - Pam = 10√6 - 9√6 = √6 mi

How do you solve this ???
galina1969 [7]
First you have to figure out how much a video game costs and how much a used one costs
Then you plug in the costs of the video games into Janets equation 120=3x+y
(x= video games and y=used video games)
Then you subtract the cost of video games  from 120 and then divide that answer by the cost of used video games and that should give you how many used video games she can get
