A computer repair shop buys fan cables from two suppliers. A west coast supplier sells the cables for $4.39 each and charges $38 to ship the order. An east coast supplier sells the cables for $3.14 each and charges $63 for shipping. How many cables (c) must the repair shop purchase so the total cost from each supplier is the same?

Simplify the expression. -2/5(10+15m-20n)

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
