m-15=3 m-15+15=3+15 m=3+15 m=18
15= M on a D M C
The average of 6, 15 and m is (6 + 15 + m) / 3 = (21 + m)/3 = 7 + m/3
15 m x 1,000 m = 15,000 m2
105
Assuming that "m" is your variable: π = 15*m Divide by 15 π/15 = m Reverse equation (reflexive property) m = π/15
15
m - 15 > m - 25
(15/m) - m + 8 = 1015/m - m = 215 - m2 - 2m = 0 or m2 +2m - 15 = 0This factoises as (m +5)( m - 3), so m = 3 or -5
1, 3, 5, 15, m, m
initial problem: 5*m=15 divide both sides by 5: m=(15)/(5) solution: m=3
It's easy to think about 1 gram as equal to 1 M&M so 15 grams would equal the weight of 15 M&M's -- approximately.
