Expand the brackets first
5(wx-v) = 9(x + v)
5wx - 5v = 9x + 9v
Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v
factorise out the x
x(9-5w) = 14v
then divide by 9-5w
x = 14v/(9-5w)
Answer:
x = 4; y = 8
Step-by-step explanation:
y=2x
y=x+4
2x = x + 4
x = 4
y = 2x = 2(4)
y = 8
Solution: x = 4; y = 8
SA=(a+b+c) h+bh
=(5+12+13)*4+5*12
=20*4+60
=80+60

Georgia worked overtime on 4 of the 5 days. Her total overtime hours were
... (12-8) +(9 -8) +(10 -8) +(10 -8) = 4 +1 +2 +2 = 9
Then her pay for the week is
... (hours) × (pay per hour)
... = ((7 + 4×8) +1.5×9) × $7.50
... = 52.5 × $7.50
... = $393.75 . . . . Georgia's gross pay for the week
_____
Pay for "time and a half" can be computed by multiplying pay by 1.5 for overtime hours, or multiplying overtime hours by 1.5 and using straight pay. Either way, it is (overtime hours)×(1.5)×(straight pay).
