Let's solve it : m + 9 = 20 === Let's try A.) Add 9 to each side. m + 9 + 9 = 20 + 9 m + 18 = 29 did not get the solution in one step === Let's try B.) Subtract 9 from each side. m + 9 - 9 = 20 - 9 m = 11 looks like the work is finished === Let's try C.) Add 20 to each side. m + 9 + 20 = 20 + 20 m + 29 = 40 did not get the solution in one step === Let's try D.)Subtract 20 from each side. m + 9 - 20 = 20 - 20 m - 11 = 0 did not get the solution in one step === Therefore, B) is the answer. The question should have asked : Which action will solve the equation in one step?
Answer #3 | 20/12 2013 00:41
B. subtract 9 from both sides.
Answer #4 | 20/12 2013 00:56
B.) Subtract 9 from each side. m = 11
Answer #5 | 20/12 2013 01:49
m + 9 = 20 subtract 9 from each side: m = 11 (B) - .--
Answer #6 | 20/12 2013 04:22
B m = 11
Answer #7 | 20/12 2013 03:03
B Obviously because to get 20, m= 11 (11+9)=20
