Answer:

Step-by-step explanation:

Let x represent the mystery number.

Create an equation to represent the situation, then solve for x:

0.85x - 5 = 29

0.85x = 34

x = 40

So, the mystery number is 40.

-4 _> 4(6y-12)-2y

first distribute/ simplify the equation
-4 _> 24y-48-2y

then combine like terms
-4 _> 22y-48

solve for y

-4 _> 22y-48
44 _> 22y
2 _> y

so the answer is y <_ 2 ( y is less than or equal to 2)
