3(18 - x/3 = -7)
54-x = -21
-x = -75
x = 75
Answer:

Step-by-step explanation:
Perimeter of rectangle = 2 × (w + h)
w = width
h = height
We have: 2 x (w + 6) = 19
w + 6 = 19 : 2 = 9.5
w = 9.5 - 6 = 3.5 (cm)

Group 17. They combine with alkali metals and form salt, the are reactive, they have 7 electrons in their outer energy level
Let H = number of hours worked.
He gets $15 for every hour worked, so you need to multiply 15 by h which is written as 15h
You then need to add that to the $200 he gets for showing up.
Total pay = 15h + 200
