Mia worked 40 hours at her two jobs last week. she earns $20 per hour at her weekday job and $18 per hour at her weekend. she earned $770 in all. how many hours did she work at each job?

x = 25

Step-by-step explanation:

x = # of hrs he worked at his weekday job

w = # of hours he worked at his weekend job

25+ x = 40y = 40 - 25 = 15.

Therefore, Mia worked for 25 hours at his weekday job and 15 hours at his weekend job.

w + x = 40

20x + 18w = 770

18(x + w = 40) = 18x + 18w = 720

(20x + 18w = 770) - (18x + 18w = 720)

2x=50

x=25

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
