Answer:
Um wat?
Step-by-step explanation:
Answer:9
Step-by-step explanation: First you add the 3x to both sides(the -4x and the -3x) and then you get 15-1x=6. Next you subtract 15 from 15 and 6, so you get -1x=-9. So then you divide both sides by -1 (do -1x over -1 equals -9 over -1). Last you do the dividing and you get x=9.
A + k = 600
k = 2/3a
a + 2/3a = 600
3/3a + 2/3a = 600
5/3a = 600
a = 600 * 3/5
a = 1800/5
a = 360
k = 2/3a
k = 2/3(360)
k = 720/3
k = 240
so Kim's pay is $ 240 and Alicia's pay is $ 360
