Well you could round it to the 4th decimal, which would be 2.7183
That as a mixed number would be $2\frac{7183}{10000} or as an improper fraction \frac{27183}{10000}$

Solve for T: T/4+8>-10 A. T>72 B> T>-72 C. T T<-72

Alinara [238K]

Answer:

$\huge\boxed{B.\ T>-72}$

Step-by-step explanation:

$\dfrac{T}{4}+8>-10\qquad|\text{subtract 8 from both sides}\\\\\dfrac{T}{4}+8-8>-10-8\\\\\dfrac{T}{4}>-18\qquad|\text{multiply both sides by 4}\\\\4\!\!\!\!\diagup\cdot\dfrac{T}{4\!\!\!\!\diagup}>(4)(-18)\\\\T>-72$
