Answer:
27 − 109 t − 10 s
Explanation:
Use Distributive Property and Simplify
9x3 =27
9x3t = 27t
27t-2t =25t
Equation so far: 27 + 25t
Next Pair of Perentheis
-10x8t =(-80t) (Remeber a Negative time a positive is still a negative)
-10xs =(-10s)
Put it all together and your answer is;
27 − 109 t − 10 s
