    Answer:

    x = 5

    Step-by-step explanation:

    The formula for the gradient is given by:

    m = (y2 – y1)/(x2 – x1), where two points (x1, y1) and (x2, y2) are given.

    Thus if we have a gradient of 2.5 and two points (3, 8) and (x, 13), we can substitute this into the above formula for the gradient to get:

    2.5 = (13 – 8)/(x – 3)

    2.5(x – 3) = 5 (Multiply both sides by (x – 3))

    x – 3 = 2 (Divide both sides by 2.5)

    x = 5 (Add 3 to both sides)

    Thus, the value of x is 5.
