Parul attempted to solve an inequality but made one or more errors. Her work and the graph she drew are shown below. Negative 5 x minus 3.5 greater-than 6.5. Negative 5 x greater-than 10. x greater-than negative 50. A number line going from negative 110 to positive 10. A closed circle is at negative 50. Everything to the right of the circle is shaded. What errors did Parul make? Select three options. She added 3.5 to both sides when she should have subtracted. She should have divided both sides by Negative 5 as her first step. She divided one side by -5 while multiplying the other side by -5. She did not change the > symbol to a < symbol. She used a closed circle instead of an open circle on the number line.
