Answer:
2.4 hours
Step-by-step explanation:
David's time = 6 hours
Anthony's time = 4 hours
the combined time is given by the following formula
1/ (david's time) + 1/(anthony's time) = 1/total time
1/6 + 1/4 = 1/Total
4/24 + 6/24 = 1/Total
10/24 = 1/ total (taking reciprocal of both sides)
24/10 = total
total time = 24/10 = 2.4 hours
Answer:
d. 4x+1
Step-by-step explanation:
(5x+3)-(x+2)
5x-x=4x
3-2=1
Final answer= 4x+1
46 cm.
do 102/17 and get 6. now take 6+6+17+17= 46 cm. that’s ur perimeter
