Distribute:(-2)(x)+(-2)(-2)=-16
Simplify:-2x+4=16
Subtract 4 from both sides:-2x+4-4=-16-4
-2x=-20
Divide both sides by -2: -2x/-2=-20/-2 x=10
Answer: X=10

-2x = -20

x = -20/-2

x = 10

Can someone plz answer this correctly and quickly.
rosijanka [135]
V = \pi \pir^{2}h

1. Find the radius. 

8/2 = 4

2. Square the radius.

4^{2} = 16

3. Multiply that by pi.

3.14 * 16 = 50.24

4. Multiply that by the height.

50.24 * 20 = 1004.8

5. Now find 60% of that.

1004.8 * 0.6 = 602.88

V = 602.88 m^{3}

Honestly, it's been a while since I've done this, but I believe this is the answer.

HELP ILL GIVE BRAINLIEST QUICK!!
Semenov [28]

Answer:

Dan is correct

Step-by-step explanation:

First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.
