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

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.
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.
pick on of the answer choices I'm not gonna fail bc of u
I apologize for any confusion. Based on the equation (x/50) - 94 = 189, the best estimate for x among the given answer choices is 15,000.
A local taqueria sold 11,321 carne asada tacos, 13,132 chicken tacos, and 8,982 carnitas tacos last year. If each taco was sold for $3.89, which value best estimates their total earnings from tacos?(1 point)

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.
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.
