Explain how to solve a system of three equations using the elimination method.

write all the equations in standard form cleared of decimals or fractions.

choose a variable to eliminate; then choose any two of the three equations and eliminate the chosen variable.

select a different set of two equations and eliminate the same variable as in step 2.

solve the two equations from steps 2 and 3 for the two variables they contain.

substitute the answers from step 4 into any equation involving the remaining variable.

check the solution with all three original equations.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98
