Step-by-step explanation: Make your denominator equal using the concept of LCM, then subtract the numerators accordingly. Rewrite each fraction to its equivilent fraction with a denominator equal to the LCM=30, then you need to subtract the numberators, but make sure to reduce your answer to the lowest possible term. I hope this helps.
The normal body temperature : to = 37° C An inequality is: | t - to | ≤ 3 | t - 37 | ≤ 3 t - 37 ≤ 3 AND ( - t - 37 ) ≤ 3 t ≤ 3 + 37 - t + 37 ≤ 3 t ≤ 40 - t ≤ 3 - 37 - t ≤ - 34 / * ( - 1 ) t ≥ 34 Answer t ∈ [ 34°C, 40° C ].
