To solve the double inequality $-8 \leq 0.2z + 3 \leq -5$, first subtract 3 from all parts: $-11 \leq 0.2z \leq -8$. Then divide everything by 0.2 to get $-55 \leq z \leq -40$.

Solve the Double Inequality −8≤0.2z+3≤−5- 8 \leq 0.2 z + 3 \leq - 5−8≤0.2z+3≤−5

Solve the Double Inequality $- 8 \leq 0.2 z + 3 \leq - 5$
