[1/1 Formula]
Work: Calculate the value of equation (20+2.1×17+3×18.5+2.5×18.6+6.2×19.1+19.5×(14.5-4.3))×0.4217-2×12×0.6494 .
Question type: Mathematical calculation
Solution:
(20+2.1×17+3×18.5+2.5×18.6+6.2×19.1+19.5×(14.5-4.3))×0.4217-2×12×0.6494
=(20+2.1×17+3×18.5+2.5×18.6+6.2×19.1+19.5×10.2)×0.4217-2×12×0.6494
=475.02×0.4217-2×12×0.6494
=200.315934-2×12×0.6494
=200.315934-24×0.6494
=200.315934-15.5856
=184.730334
Answer:(20+2.1×17+3×18.5+2.5×18.6+6.2×19.1+19.5×(14.5-4.3))×0.4217-2×12×0.6494=184.730334
