J. r. tossed a coin 100 times. fill in the boxes to complete each statement. based on j. r's results, the probability of tossing heads is % this is than the theoretical probability of tossing heads with a coin.(on graph, tails is 60 number of tosses and heads is at 40 number of tosses)

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
