Question

Please help!! Math!!!!

Answer 1

5 - 3z < -10

-5          -5  minus 5 from both sides

-3z  <  -15

/-3         /-3  Divide both sides by 3 and when you divide by a negative you    

                   switch the inequality sign from < to >

z > -5

Answer 2

Hello!

Explanation:

First, you had to do is subtract by 5 from both sides of an equation.

$5-3a-5$

And then simplify.

$10+5=15$

$-3a$

Next, you can also multiply by -1 from both sides of an equation. It can also used by reverse inequality.

$(-3a)(-1)>(-15)(-1)$

Simplify by equation.

$3a>15$

Then you divide by 3 from both sides of an equation.

$\frac{3a}{3}> \frac{15}{3}$

Finally, simplify or dividing into the groups.

$15/3=5$

*The answer must have a positive sign*

Final answer: → $\boxed{a>5}$

Hope this helps!

Thanks!

Have a great day!
