[1/1 Formula]
Work: Calculate the value of equation (20+19.4×3.00+18.7×1.0+17.8×2.40+18.2×2.10)×0.689-2×0.830×12 .
Question type: Mathematical calculation
Solution:
(20+19.4×3.00+18.7×1.0+17.8×2.40+18.2×2.10)×0.689-2×0.830×12
=177.84×0.689-2×0.830×12
=122.53176-2×0.83×12
=122.53176-1.66×12
=122.53176-19.92
=102.61176
Answer:(20+19.4×3.00+18.7×1.0+17.8×2.40+18.2×2.10)×0.689-2×0.830×12=102.61176
