Ikind of get the question, i got the inequality 1.5x+9.75y < = 50; however, i don't know how to solve it or get the # of ebooks.

let x represent the number of songs, and let y represent the number of ebooks.

0 ≤ y ≤ 5

Step-by-step explanation:

As you found, the inequality is:

1.5x + 9.75y ≤ 50

The most e-books Kim can buy is when x = 0.

9.75y ≤ 50

y ≤ 5.13

y must be an integer, so the number of e-books Kim can buy is 0 ≤ y ≤ 5.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
