To find the value of x in the equation -2x + 902 = 1,518, we need to isolate the variable x.

First, subtract 902 from both sides of the equation:
-2x + 902 - 902 = 1,518 - 902
-2x = 616

Next, divide both sides of the equation by -2 to solve for x:
-2x / -2 = 616 / -2
x = -308

Therefore, the best estimate for x is -300 or negative 300.

To find the total number of cells in the laboratory, we need to add the number of cells in each petri dish.

First, add the number of cells in the three petri dishes:
22,340 + 43,560 + 36,612 = 102,512

Therefore, approximately there are 102,512 cells in total.

To find the value of x in the equation (x/50) - 94 = 189, we need to isolate the variable x.

First, add 94 to both sides of the equation:
(x/50) - 94 + 94 = 189 + 94
(x/50) = 283

Next, multiply both sides of the equation by 50 to solve for x:
50 * (x/50) = 283 * 50
x = 14,150

Therefore, the best estimate for x is 14,150.

To find the total earnings from tacos, we need to multiply the number of each type of taco sold by the price of each taco and then sum up the results.

The number of carne asada tacos sold: 11,321
The number of chicken tacos sold: 13,132
The number of carnitas tacos sold: 8,982

The price of each taco: $3.89

To calculate the total earnings, we multiply each quantity by the price:

11,321 * $3.89 = $44,001.69
13,132 * $3.89 = $51,009.48
8,982 * $3.89 = $34,912.98

Adding up these amounts gives us:

$44,001.69 + $51,009.48 + $34,912.98 = $129,924.15

Therefore, the value that best estimates their total earnings from tacos is $130,000.

To find the value of x in the equation 21x + 1,998 = 2,243, we need to isolate the variable x.

First, subtract 1,998 from both sides of the equation:
21x + 1,998 - 1,998 = 2,243 - 1,998
21x = 245

Next, divide both sides of the equation by 21 to solve for x:
(21x) / 21 = 245 / 21
x = 11.67

Therefore, the best estimate for x is 10.
