Final answer:
The value of a + bc + d is 1.025.
Step-by-step explanation:
To evaluate the expression a+bc+d, we substitute the given values for a, b, c, and d and perform the necessary calculations:
a = -3.6
b = 2 5/4
= 2.25
c = -1/2
d = 6 3/4
= 6.75
Now we can plug in these values:
a + bc + d = -3.6 + (2.25)(-1/2) + 6.75
= -3.6 - 1.125 + 6.75
= 1.025
Therefore, the value of a + bc + d is 1.025.
