1231 x (112%×50%)+(100%×50%)=
Answer (4)
3f+3=t s=2f 21=f+s+t
21=f+(2f)+(3f+3) 21=6f+3 18=6f
3=first 6=second 12=third
The three pieces of the steel bar are 3 inches , 6 inches, and 12 inches long, respectively. ;
The lengths of the three pieces of steel are 3 inches, 6 inches, and 12 inches. The first piece is represented by x , the second is twice that, and the third is three times the first plus 3 inches. This gives us a total length of 21 inches when combined.
