Answer 1

its 200

Answer 2

To find the value of x, you need to isolate it on one side of the equation.

Starting with the given equation: 4x - 189 = 578

First, add 189 to both sides of the equation to eliminate the constant term on the left side:

4x - 189 + 189 = 578 + 189
4x = 767

Then, divide both sides of the equation by 4 to solve for x:

4x/4 = 767/4
x = 191.75

Therefore, the estimated value of x is 191.75.

Answer 3

I apologize for the error in my previous response. You are correct.

When solving the equation, 4x - 189 = 578, and adding 189 to both sides, we get:

4x = 767

Then, dividing both sides by 4, we have:

x = 191.75

However, in this case, we are asked to estimate the value of x. Since 191.75 is not a whole number, we can round it up or down to the nearest whole number. The nearest whole number to 191.75 is 192.

Therefore, the estimated value of x is 192, not 200. Thank you for pointing out the mistake.
