Answer:
he attempted 30 shots
Step-by-step explanation:
60 percent of 30 is 18 and 40 percent of 30 is 12 so you at 12 plus 18 and get 30
If each garden takes 20 minutes to clean, it will take him (20 x 4) to clean the gardens.
20 x 4 = 100
80 minutes
or 1 hour and 10 minutes.
(–1)8 + (–1)7 + –16 + –14 – (–1)2 = -8 -7 -16 -14 +2 = -45+2 = - 43
