Work: Calculate the value of equation 0.283×(18.7×3.9+19×(9.2-3.9)+9.4×(3.9+6.7-9.2)+10.1×3.1+20)+10×(3.9+6.7-9.2+3.1) .
Question type: Mathematical calculation
Solution:
0.283×(18.7×3.9+19×(9.2-3.9)+9.4×(3.9+6.7-9.2)+10.1×3.1+20)+10×(3.9+6.7-9.2+3.1)
=0.283×(18.7×3.9+19×5.3+9.4×(3.9+6.7-9.2)+10.1×3.1+20)+10×(3.9+6.7-9.2+3.1)
=0.283×(18.7×3.9+19×5.3+9.4×1.4+10.1×3.1+20)+10×(3.9+6.7-9.2+3.1)
=0.283×238.1+10×(3.9+6.7-9.2+3.1)
=0.283×238.1+10×4.5
=67.3823+10×4.5
=67.3823+45
=112.3823
Answer:0.283×(18.7×3.9+19×(9.2-3.9)+9.4×(3.9+6.7-9.2)+10.1×3.1+20)+10×(3.9+6.7-9.2+3.1)=112.3823
