3x+8y=−6

Can someone me with this problem . show your work .

15m is what percent of 60m; 3m; 30m; 1.5 km? the last one is km not m

Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m? -15m = -4m -7m - 8 = m - 4 -3m - 8 = 4 - m m - 4 = -7m - 8 -8 - 7m = -4 + m -8 - 3m = 4 - m
