Each peice is 1.5 inches
7*1.5=10.5
The dowel was 10.5 inches long
I'm sorry, I hope this helped.
(7.8 x 10⁵ meter/hour) x (24 hour/day) x (1 kilometer / 1,000 meter) =
[ (7.8 x 10⁵ x 24 x 1) / (1,000) ] x [ kilometer / day ] = 18,720 km/day
Minus 4x from both sides
x+3=0
minus 3 from both sides
x=-3
