Answer:

1/2b - 5 (the third one)

Step-by-step explanation:

"Denni is five years less..."

this tells us we will need to be subtracting five, which knocks out the other answers.

"..one-half his brothers age."

since b represents the age of his brother, one half his brothers age is 1/2b

That leaves us with 1/2b - 5

-5x -10 >30 help Hehehehehe.

Mnenie [13.5K]

Answer:

x<-8

Step-by-step explanation:

-5x-10>30

(add 10 to both sides)

-5x-10+10>30+10

-5x>40

$\frac{-5x}{-1}$ < $\frac{40}{-1}$

(dividing through by -1 changes the sign of the inequality from "<" to ">")

5x<-40

(dividing through by 5)

$\frac{5x}{5}$ < $\frac{-40}{5\\}$

x<-8
