Answer:
key is 18
exit tag is 15
lock is 14
key*tag*lock = 3780
Step-by-step explanation:
54/3 is 18 so each key is 18
48-key = 30 so each tag is 15 since 15+15 = 30
18*15*14=3780
Answer:
8,13,21
Step-by-step explanation:
Basically,add the previous number to next number
The answer is 73567374 so even
30 min: 60min-30min= 30 min and 30 min is half an hour. So since 30 min is half an hour you divide 4 by 2 and get 2 miles.
45 min: 60min-45min= 15 min. 15 is one quarter of an hour so, since you are going 4mph. So you do 4mph divided by another for because there are four quarters in one hour, which gives you one mile. Then you 1 mile 3 times because 15+15+15=45. So the answer is 3 miles.
2 hours: 2x4= 8 miles
3 hours: 3 hours x 4mph= 12 miles
3x+5y= 20
3(10)+5y= 20
30+5y= 20
-30 -30
——————
5y=-10
———-
5 5
y = -2
(10,-2)
Answer: (10,-2)
