Answer:

Since there are 4.5*10^2 grams of trash per day per person, we multiply that by 3.2*10^6 for everyone in the US and then multiply that by 365 to get how much in a year, which is 525600000000 or 5.256*10^11 (I think it's 11)

Your neighbor had to drop the selling price of her home from $180,000 to $165,000. What percent did the price get lowered? Round
Vikki [24]
You could do 165,000 divided by 180,000. This is 165000/180000, and that will give you the percentage that 165000 is of 180000 in decimal form, which is 0.9167.
Then we round to the nearest tenth, which is 0.92
0.92 as a percentage is 92%.
100% - 92% = 8%
The price of the home dropped by 8%.

Solve the equation. −3(y+5)=15
e-lub [12.9K]

Divide both sides by -3

y + 5 = -15/3

Simplify 15/3 to 5

y + 5 = -5

Subtract 5 from both sides

y = -5 - 5

Simplify -5 - 5 to -10

y = -10
