Which of the following answers gives the best estimate for x given the following equation?
21x+1,998=2,243
To estimate the value of x in the equation 21x + 1,998 = 2,243, we can solve for x.
First, we isolate the x term by subtracting 1,998 from both sides of the equation:
21x + 1,998 - 1,998 = 2,243 - 1,998
21x = 245
Next, we can divide both sides of the equation by 21 to solve for x:
21x/21 = 245/21
x = 11.6667
The best estimate for x is therefore approximately 11.6667.
