Answer:
Step-by-step explanation:
Length of the bridge = 190 m = 190*100 = 19000 cm {100cm = 1m}
Length of each pace of Robert = 80 cm
Minimum number of full paces = 19000/80
= 237.5
= 238 {because full paces}
Break the expression into two groups, then if you factor out what you need to do, then factor out the common term, you'll end up with ( 3x - 11 ) ( x - 10 )
27÷3=9
9 is the original number.
9×2=18
the answer is 18.
