Step-by-step explanation:
Hey, there!!
I hope you mean to subtract (-137) +(-43) from sum of -103 and 27.
First, add -103 + 27


{As ( minus + plus )= subtracts with sign which has greator value. }
now,

{ minus + minus = add with minus sign}.
Now, subtracting -180 from -76.
=(-76) - (-180 )
Now, multiply the sign (- × -)= +
so, -180 becomes +180
= -76+180
= 104..... is answer.

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.
No matter what number you substitute for y, this equation will be untrue.
It has zero solutions.
