A+S=589
S=a-61
A+A-61=589
2a=589+61
2a=650
A=325
S=325-61
S=264

Answer:
an = 2 + n
Step-by-step explanation:
The differences between terms are all 1. The first term is 3. The general form of the general term is ...
an = a1 + d(n -1)
Filling in a1 = 3 and d = 1, we have ...
an = 3 + n - 1
an = 2 + n . . . . . . simplify
Answer:
9:15 am
Step-by-step explanation:
Alarms sound at 7:15 am
Alarm frequencies are 40 min and 60 min
Since 40= 20*2 and 60= 20*3, the overlapping frequency is:
- 20*2*3= 120 min = 2 hours
So next time both alarms sound at 7:15 am + 2 hours = 9:15 am
X=number of gallons that she must order.
4 gallons-----------------3 weeks
(7 gallons + x)--------12 weeks
We solve this rule of 3.
(7 gallons +x)3 weeks=4 gallons*12 weeks
21 gallons weeks+3 x weeks=48 gallons weeks
3x weeks=48 gallons weeks - 21 gallons weeks
3x weeks=27 gallons weeks
x=(27 gallons weeks) / 3 weeks=9 gallons.
Solution: she must order 9 gallons more.
