Where could you insert parentheses in the problem 310-20÷2×5+13 so the answer should be 130

The parenthesis should be placed in 310-20/2 x (5 + 13) =130

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
