which of the following answers gives the best estimate for x given the following equation
-2x + 902 = 1,518
-600
-300
300
600
To find the best estimate for x, we need to solve the equation -2x + 902 = 1,518.
Adding 2x to both sides, we get:
902 = 2x + 1,518
Subtracting 1,518 from both sides, we get:
-616 = 2x
Dividing both sides by 2, we get:
-308 = x
Therefore, the best estimate for x is -300.
