Final answer:
The equation (18/10) + x = (29/5) represents the given relationship, and the value of x is 4.
Step-by-step explanation:
To find the equation and value of x that represent the given relationship, we can set up the equation (18/10) + x = (29/5). To solve for x, we can subtract (18/10) from both sides of the equation:
x = (29/5) - (18/10)
To simplify the right side of the equation, we need a common denominator of 10:
x = (58/10) - (18/10) = (58-18)/10 = 40/10 = 4
Therefore, the equation (18/10) + x = (29/5) represents the relationship and the value of x is 4.
