Evaluate 8c+5d when c=-3 and d=4
To evaluate 8c + 5d when c = -3 and d = 4, we substitute these values into the expression:
8c + 5d = 8(-3) + 5(4)
Multiplying, we get:
24 + 20 = 44
Therefore, 8c + 5d when c = -3 and d = 4 is equal to 44.
To evaluate the expression 8c + 5d when c=-3 and d=4, substitute these values into the expression:
8(-3) + 5(4)
Multiply first:
-24 + 20
Now, add:
-4
Therefore, 8c + 5d when c=-3 and d=4 is equal to -4.
