Which of the following answers gives the best estimate for x given the following equation? 21x+1,998=2,243 (1 point) Responses 100 100 10 10 1 1 1,000
To find the value of x, we need to isolate x on one side of the equation. Start by subtracting 1,998 from both sides:
21x + 1,998 - 1,998 = 2,243 - 1,998
21x = 245
Then, divide both sides of the equation by 21:
21x/21 = 245/21
x = 11.6667
However, none of the given answer choices is the best estimate for x.
are you sure
Apologies for the confusion. I made an error in the calculations. Let's solve the equation correctly:
21x + 1,998 = 2,243
We can subtract 1,998 from both sides:
21x = 2,243 - 1,998
21x = 245
To isolate x, we divide both sides by 21:
21x/21 = 245/21
x = 11.6667
So, x is approximately 11.6667.
To find the best estimate for x in the equation 21x + 1,998 = 2,243, we need to isolate x on one side of the equation. Here's how we can do it step by step:
1. Start by subtracting 1,998 from both sides of the equation:
21x + 1,998 - 1,998 = 2,243 - 1,998
This simplifies to:
21x = 245
2. Next, divide both sides of the equation by 21 to solve for x:
21x / 21 = 245 / 21
This simplifies to:
x = 11.6666667
Out of the provided answer choices (100, 10, 1, 1, 1,000), none of them are equal to the exact solution of x = 11.6666667. Therefore, none of the provided answer choices are the best estimate for x in this equation.
