[Done] Samuel's Car Service charges a flat travel fee of $4.75 per trip. They also charge an additional rate of $1.50 per mile traveled. What is an equation that represents the charges? 1) \( y = 1.5x + 1.5 \) 2) \( y = 4.75x + 4.75 \) 3) \( y = 1.5x + 4.75 \) 4) \( y = 4.75x + 1.5 \)

[Done] What are the possible values for x in the equation [tex]4x^2 = 64[/tex]? 1) [tex]x = 0[/tex] 2) [tex]x = 4[/tex] 3) [tex]x = 4, -4[/tex] 4) [tex]x = 0, 4, -4[/tex]

[Done] A jet travels 3950 miles from Chicago to London and then returns. The total flying time for the round trip is 16.5 hours. The return trip takes longer due to the wind. If the jet's average speed with no wind is 485 mi/hr, what is the average speed of the wind during the round trip flight? Round to the nearest mi/hr.

[Done] Given the equation: \[(3x + 2)(2x - 5) = ax^2 + kx + n\] What is the value of \(a - n + k\)?

[Done] Move the decimal point in 250,000 to the left as many places as necessary to find a number that is greater than or equal to 1 and less than 10.

[Done] List the next four multiples of the fractions: - \(\frac{2}{3}\) - \(\frac{5}{6}\) - \(\frac{3}{5}\) - \(\frac{2}{5}\)

[Done] Use long division to find the quotient, \( q(x) \), and remainder, \( r(x) \). \[ \frac{x^2 - 2x - 15}{x - 5} \]

[Done] List one way a parallelogram and a rhombus are different.

[Done] What is the product of \(-3x^2y\) and \((5xy^2 + xy)\)?
