Answer: See explanation

Step-by-step explanation:

Let the possible number of CDs that she could buy be represented by x. Then, the equation can be represented as:

80 - 18x ≤ 20

80 - 20 ≤ 18x

60 ≤ 18x

x ≤ 60/18

x ≤ 3.33

The highest amount of cd that she can is 3 or less.

Answer:

8.0

Step-by-step explanation:

The triangle is a right triangle, so we are able to use trigonometric functions. Relative to the angle of 37°, we have the opposite side which is 6 and the adjacent side which is x. The trig function that uses the opposite and adjacent is tangent(SohCahToa). We can set up the following equation:

tan(37) = \frac{opposite}{adjacent}

tan(37) = \frac{6}{x}

tan(37) evaluates to about , so we can plug it in and solve for x:

0.7536 = \frac{6}{x} \\0.7536x = 6\\x = 7.962

To the nearest tenth, x rounds to 8.0.
