X/2 + 5= -8 what does x equal and show work

Answers

Answer:

x = -26

Step-by-step explanation:

x/2 + 5 = -8

First let's combine like terms.

Subtract 5 from both sides.

x/2 = -13

Multiply both sides by 2 to isolate x.

x = -26

Plug this back into the original equation to check your answer.

-26/2 + 5 = -8

-13 + 5 = -8

-8 = -8

Your answer is correct.

Hope this helps!

Answer:

x=-26

Step-by-step explanation:

x/2 + 5 = -8

x/2 + 5 - 5 = -8 - 5

x/2 = -13

x = -26

this is all of the work I did to solve what x is! I hope it helped! There are many other way to solve this problem. This is the way which a lot of ppl do.

The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially. How many grams of the substance are left after 300 years?

Answers

Answer:

There are 2,000 grams left after 300 years.

Step-by-step explanation:

Giving the following information:

The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.

First, we need to calculate the reduction of the substance each year:

Yearly reduction= 8,000/400= 20 grams per year

Now, for 300 years:

300 year reduction= 20*300= 6,000

There are 2,000 grams left after 300 years.
