The answer would be 1 million because if the average person lives to be 70 multiply that by 2000 and you get 51100000 so I would say that total is closer to 1 million then it is to 3 billion

3 + 2(2x + 8) = 1 is equivalent to:

suter [353]

Answer:

x = $-\frac{9}{2}$

Step-by-step explanation:

=> 3+2(2x+8) = 1

=> 3+4x+16 = 1

=> 4x+19 = 1

=> 4x = 1-19

=> 4x = -18

<u><em>Dividing both sides by 4</em></u>

=> x = $-\frac{18}{4}$

=> x = $-\frac{9}{2}$

please HELP MEEEEEE .A store owner wants to make a candy that sells for $1 per pound.he has 50 lb of sugar candies that cost $1.

serious [3.7K]

Answer:

50 pounds

Step-by-step explanation:

we can use the equation 60+80/100x=1(x+50)

we get 80/100 x because the gummy candies are 80 cents or 80/100x

we get 60 from multiplying 1.20$ x 50 = 60

solve:

60+80/100x = x+50

60 = x-80/100x+50

60-50 = 20/100x

10 = 20/100x

x= 10 x 100/20 = 10x5= 50 pounds
