Answer:
820
Step-by-step explanation:
So first you add 40 percent and 30 percent to get 70 percent. After you do that subtract it from 100 to get 30. 30% times 30 is 9 so the answer is 9 cds.
-3y + 7 = y - 6(¹/₂y + 2)
-3y + 7 = y - 6(¹/₂y) - 6(2)
-3y + 7 = y - 3y - 12
-3y + 7 = -2y - 12
+ 3y + 3y
7 = y - 12
+ 12 + 12
19 = y
