Justin is asked to solve the following system of linear equations using the elimination method. 5x − 12y = 3
−20x + 14y = 13

Which of the coefficients should Justin try to change so that it cancels with another coefficient?

Apackage of bacon holds 15 strips of bacon. the pancake house uses 17 packages of bacon in the morning and 21 packages in the afternoon. how many more strips were used in the afternoon than the morning?

()1. how do you find range? 2.the following set of data is to be organized into a histogram. if there are to be five intervals on the graph, what should the length of each interval be? 30, 34, 23, 21, 27, 25, 29, 29, 25, 23, 32, 31

If the wwight of a package is multiplied by 7/10 the result is 65.8 find the weight of the package
