Answer d, because the equation is stating 3= $4.41, we are trying to figure out how much 4 cost
Ipatiy [6.2K]3 years ago
3 0
So d is correct as if u wanted to find out how much one thing cost u need to divide the number of the thing by its cost .An example is 20dollars for 4 apples. so 20/4=5 dollars for each apple. 

This equation shows how much 3 erasers cost, which in this case its 4.41. the equation equals to 4/x as the cost of 1 eraser is the same. so if u wanted to solve this equation, u can use the cross method to multiply it so 

3x=4.41*4
3x=<span>17.64
x=</span><span>5.88</span>

The equation 2x + 4k − 9 = kx − k + 1 is really a family of equations, because for each value of k, we get a different equation
Olegator [25]
You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.

Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.

2(4) + 4k - 9 = (4)(4) - (4) + 1

Then 8 + 4k - 9 = 16 - 4 + 1, or       4k - 1 = 13.  Then 4k = 14, and k = 14/4, or (after reduction)  k = 7/2   

If the parameter k equals 7/2, then x = 4 is a solution to the given equation.

To check this out further, start with the proposed solution x = 5 and find k.
