Divide: 7/3: 1/5= 7/3· 5/1= 7 · 5/3 · 1= 35/3
10 + (-5) = 10 - 5 = 5
-11 + 20 = 20 + (-11) = 20 - 11 = 9
102 + (-1) = 102 - 1 = 101
<span>-20 + 60 = 60 + (-20) = 60 - 20 = 40 </span>
<span>x^3=8/125
x^3 = 2^3 / 5^3
x = 2/5

The total temperature of the magnesium sample is its original temperature plus the temperature increase which is dependent on time. This total should exceed 650 degrees. Thus, the inequality that best describes the condition is,
255 + 10m ≥ 650
m ≥ 39.5
The answer is letter b.
