Answer:

0.75x + 0.15y = 90

greatest number of pens =120

greatest number of pencils = 600

Step-by-step explanation:

Let x represent the number of pens

Let y represent the number of pencils.

Each pen costs $0.75

Cost of x pens = 0.75 x

Each pencil costs $0.15.

Cost of y pencils = 0.15y

Now we are given that The glee club has $90 to spend on pens and pencils.

So, 0.75x + 0.15y = 90

So,t the equation that describes the number of club pens and pencils that the glee club can buy is  0.75x + 0.15y = 90

Part A)  0.75x + 0.15y = 90

Part B )What is the greatest number of each type of writing tool that the club can buy?

0.75x + 0.15y = 90

Substitute y = 0

0.75x = 90

x = \frac{90}{0.75}

x = 120

greatest number of pens =120

Substitute x = 0

0.15y= 90

y = \frac{90}{0.15}

y = 600

greatest number of pencils = 600

The area of a rectangular piece of cardboard is represented by
Liula [17]

This question is solved applying the formula of the area of the rectangle, and finding it's width. To do this, we solve a quadratic equation, and we get that the cardboard has a width of 1.5 feet.

Area of a rectangle:

The area of rectangle of length l and width w is given by:

A = wl

w(2w + 3) = 9

From this, we get that:

l = 2w + 3, A = 9

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}

x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}

\Delta = b^{2} - 4ac

In this question:

w(2w+3) = 9

2w^2 + 3w - 9 = 0

Thus a quadratic equation with a = 2, b = 3, c = -9

Then

\Delta = 3^2 - 4(2)(-9) = 81

w_{1} = \frac{-3 + \sqrt{81}}{2*2} = 1.5

w_{2} = \frac{-3 - \sqrt{81}}{2*2} = -3

Width is a positive measure, thus, the width of the cardboard is of 1.5 feet.
