The relationship between the total cost and the costs of CDs and DVDs are represented by a linear function.

The cost of 6 CDs and 2 DVDs is $147.68 Let: From the question, we have: Substitute in Collect like terms Divide both sides by 7 Substitute in The cost of 6 CDs & 2 DVDs is represented as: So, we have: Hence, the cost of 6 CDs & 2 DVDs is$147.68

6 CDs and 2 DVDs would cost $147.68. Let c be the cost of a CD and d be the cost of a DVD. We know that c = d+5.96. We also know that 5c+2d = 127.73. Substituting our value of c from the first equation into the second one, we have 5(d+5.96)+2d = 127.73 Using the distributive property, 5*d+5*5.96+2d = 127.73 5d+29.80+2d = 127.73 Combining like terms, 7d+29.80 = 127.73 Subtract 29.80 from both sides: 7d+29.80-29.80=127.73-29.80 7d = 97.93 Divide both sides by 7: 7d/7 = 97.93/7 d = 13.99 c = d + 5.96 = 13.99+5.96 = 19.95 6 CDs and 2 DVDs would be 6(19.95)+2(13.99) = 147.68 ## ðŸ“š Related Questions Question Rectangle J'K'L'M' shown on the grid is the image of rectangle JKLM after transformation. The same transformation will be applied on trapezoid STUV. Rectangle JKLM is drawn on the grid with vertices J at negative 5, 1. K is at negative 5, 6. L is at negative 7, 6. M is at negative 7, 1. Rectangle J prime K prime L prime M prime is drawn with vertices at J prime 4, 4. K prime is at 4, 9. L prime is at 2, 9. M prime is at 2, 4. Trapezoid STUV is drawn with vertices at S is at 9, negative 6. T is at 9, negative 2. U is at 7, negative 2. V is at 6, negative 5. What will be the location of U' in the image trapezoid S'T'U'V'? (16, âˆ’2) Solution 1 U' will be at (16, 1). The transformation that maps JKLM to J'K'L'M' is a translation 9 units right and 3 units up. The same transformation is applied to STUV; this means that U(7, -2) will be mapped to U'(7+9, -2+3) = U'(16, 1). Solution 2 Answer: U' will be at (16, 1). Step-by-step explanation: Question A polyhedron has 10 faces and 24 edges. Use Euler's Formula to find the missing number of vertices. Solution 1 Â Euler's Formula :Â VÂ -Â EÂ +Â FÂ = 2Â Given that F = 10 and E = 24 V - 24 + 10 Â = 2 V - 14 Â = 2 V = 16 Answer: Vertices = 16 Solution 2 Hey user!! your answer is here... we know that Euler's formula = F + V - E = 2 given :- faces = 10 verticies = ? edges = 24 therefore F + V - E = 2 ==> 10 + V - 24 = 2 ==> -14 + V = 2 ==> V = 2 + 14 ==> V = 16 verification :- = F + V - E = 10 + 16 - 24 = 26 - 24 = 2 hence verified.. thus the no. of verticies of the polyhedron is 16. cheers!!

Question
______________ is process that you can do over and over, where each result does not affect the next. Ex. Flipping a coin, rolling dice, choosing a card, etc.
Solution 1
In probability, an experiment is any procedure that can be infinitely repeated and has a well-defined set of possible outcomes. Thus, an experiment is a process that you can do over and over, where each result does not affect the next. For example: Flipping a coin, rolling dice, choosing a card, etc. are all experiments.
