Answer:
I believe the solution of the system of equations in (5,-7)
Step-by-step explanation:
7000 = 7 x 1000 = 7 x 10^4
Answer: 7 x 10^4
Pay=pay per minute times minutes
find how many minutes
1hr=60 mins
times 5
5hr=300mins
7 days
300min per day
ties 7
2100mins total
pay=salary rate times mins
pay=2 times 2100
pay=4200
makes $4200 per week
(he makes $120 per hour, that's alot!)
4,464 divided by 18 is 248
Alan is 14 years old
He is twice as old as James
then Alan is the elder brother
Alan is twice as old means his age is double the age of James
Alans age = 2 x james age
that means James must be half of Alans age
Alans age = 14 years
James age = 14 / 2 = 7 years
therefore James is 7 years old
