You can stuff envelopes twice as fast as your friend. Together, you can stuff 6750 envelopes in 4.5 hours. How long would it tak

Lynna [10]

If you're twice a fast then... we'll divide 6750 by 3, that equals 2250.
<span>Equation.. y=your friend and you would be 2y cuz you're twice as fast.
</span>y+2y=6750,
3y=6750
y=2250

Your friend stuffed 2250 in 4.5 hrs.
You (twice as fast) stuffed 4500 in 4.5 hrs.

Working alone, your friend can stuff 2250 in 4.5hrs so it would take 13.5hrs to stuff 6750.
Equation.. (6750/2250) x 4.5hrs = 13.5hrs

You can 4500 in 4.5hrs so it would take you 6.75 hrs to stuff 6750.
Equation.. (6750/4500) x 4.5hrs = 6.75 hrs.

Answer:

Step-by-step explanation:

$t=2\dfrac{2}{3}\ h=\dfrac{2\cdot3+2}{3}\ h=\dfrac{8}{3}\ h\\\\r=36\ mph\\\\\text{Substitute to}\ d=rt:\\\\d=36\!\!\!\!\!\diagup^{12}\ \dfrac{mi}{h\!\!\!\!\diagup}\cdot\dfrac{8}{3\!\!\!\!\diagup_1}\ h\!\!\!\!\diagup=(12\ mi)(8)=96\ mi$

Hi, please help me with the answers for the following questions. For this type of assignment, you make your own algebraic expres

The quotient of a trinomial and monomial can be 9x² +2x + 1 while the product of the polynomials x² + 2x + 1 and 3x² - 1 is 3x⁴ + 6x³ + 2x² - 2x - 1

<h3>The quotient of a trinomial and monomial</h3>

Let the variable be x.

Trinomial are polynomials that have three terms, while monomials have a single term.

Using the above definition, we have:

Trinomial = 9x³ + 2x² + x

Monomial = x

The quotient of the above is represented as:

$\frac{9x^3 +2x^2 + x}{x}$

Evaluate the quotient

9x² +2x + 1

<h3>The product or quotient of polynomials</h3>

To do this, we make use of the following polynomials:

x² + 2x + 1 and 3x² - 1

The product is represented as:

(x² + 2x + 1) * (3x² - 1)

Expand

3x⁴ - x² + 6x³ - 2x + 3x² - 1

Evaluate the like terms

3x⁴ + 6x³ + 2x² - 2x - 1

Hence, the product of the polynomials x² + 2x + 1 and 3x² - 1 is 3x⁴ + 6x³ + 2x² - 2x - 1
