Answer:

z > -2

Explanation:

Given inequality: -5z > 10

To determine the simplified inequality, we need to isolate "z". Divide -5 both sides to isolate the variable "z".

⇒ -5z > 10

⇒ -5z/-5 > 10/-5

Always remember that if you are dividing by a negative number, the inequality sign flips over.

⇒ z < -2

Thus, the simplified inequality is z < -2.

Answer:


  • \boxed{\sf{z < -2}}

Explanation:

To solve for z, isolate it on one side of the equation.

-5z>10

First, multiply by -1 from both sides.

⇒ (-5z)(-1)<10(-1)

Solve.

Multiply the numbers from left to right.

⇒ 10(-1)=(-10)

Rewrite the problem down.

⇒ 5z<-10

Then, you divide by 5 from both sides.

⇒ 5z/5<-10/5

Solve.

Divide the numbers from left to right.

⇒ -10/5=-2


\boxed{\sf{z < -2}}

  • Therefore, the correct answer is z<-2.

I hope this helps you! Let me know if my answer is wrong or not.
