Which of the following answers gives the best estimate for x givin the following equation? 21x+ 1,998=2,243 answer choices 1,1,000,10,100
To solve the equation 21x + 1,998 = 2,243, we need to isolate the variable x.
We can begin by subtracting 1,998 from both sides of the equation:
21x + 1,998 - 1,998 = 2,243 - 1,998
21x = 245
Next, we divide both sides of the equation by 21 to solve for x:
21x/21 = 245/21
x = 11.67
Therefore, none of the given answer choices (1, 1,000, 10, 100) are the best estimate for x. The best estimate for x is approximately 11.67.
