Final answer:
To evaluate the expression 3 4/5 x - 2 1/2 for x = -10, substitute x = -10 into the expression, simplify the expression, and obtain the evaluated expression as -25.
Step-by-step explanation:
To evaluate the expression 3 4/5 x - 2 1/2 for x = -10, we substitute x = -10 into the expression:
3 4/5 x - 2 1/2 = 3 4/5 (-10) - 2 1/2
Next, we simplify the expression:
3 4/5 (-10) = 3 * (4/5) * (-10) = -24
Similarly, 2 1/2 = 2 * (1/2) = 1
So, the evaluated expression is:
3 4/5 x - 2 1/2 = -24 - 1 = -25
