we want to in 85% of the total population

percent means parts out of 100 so 85% is 85/100

85% 'of' 15000 means 85/100 times 15000=12750 people who were over 40 and voted

What solution is this w = 10

alina1380 [7]

Answer:

w = 10

Step-by-step explanation:

9(w - 9) -2 = -7 + 7(w -8)

Expand:

9w - 81 - 2 = -7 + 7w - 56

Rearrange:

9w - 7w = -7 - 56 + 81 + 2

2w = 20

w = 10

Answer:

I did my best, but it has been a while. I really hope that this helps

Step-by-step explanation:

so you can find the perimeter of a circle

-----The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle, you need to go halfway around the circle and then across a diagonal to get back to where you started, so the perimeter is 1/2 π × d + d.
