suppose the population of a certain city is 3195 thousand. it is expected to decrease to 2546 thousand in 50 years. find the percent decrease.

Hey there! I'm happy to help!

We see that 3195 minus a certain percent of 3195 is equal to 2546. Let's call this percent decrease p and then solve.

3195-3195p=2546

We subtract 3195 from both sides.

-3195p=-649

We divide both sides by -3195.

p≈0.20312989

To convert to a percent, we multiply by 100, giving us about 20.3% decrease.

Have a wonderful day! :D

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
