Answer:

1780s to 1830s

Step-by-step explanation:

Pollution is not a new phenomenon. In fact, pollution has been a problem since the appearance of our earliest ancestors (Markham, 1994). Increasing human populations have opened the door to more bacteria and disease. During the Middle Ages, diseases such as cholera and typhoid fever broke out all across Europe.

Someone please send help lol. I made a recursive statement for a project but I'm not exactly the best with solving them.
Kitty [74]

Answer:

It would take 4 weeks

Step-by-step explanation:

We can solve this problem most easily by forming it into an equation. We could represent weeks as <em>w.</em>

Since you train 5 more minutes every week, we could represent that as 5<em>w</em>, showing that you work 5 minutes times the number of weeks you worked out.

The constant would be adding 10, since you started out working 10 minutes a day. Now lets just write the equation!

10+5<em>w</em>=30

All we have to do is solve.

Subtract 10 on both sides to cancel out the positive 10.

5<em>w</em>=20

Now just divide both sides by 5 to isolate the <em>w</em>.

w=4

It would take him 4 weeks

Hope this helps!
