If a = 6, b = 3, and c = 7, evaluate the following expression:
start fraction 3 left parenthesis 4 a minus 3 c right parenthesis over c minus 4 end fraction
84
147
3
one-third
To evaluate the expression, we substitute the given values of a, b, and c into the expression:
Start by calculating 4a: 4 * 6 = 24
Next, calculate 3c: 3 * 7 = 21
Now we substitute these values into the expression:
(3(24) - 21) / 7 - 4
= (72 - 21) / 7 - 4
= 51 / 7 - 4
= 7.3 - 4
= 3.3
Therefore, the value of the expression is 3.3.
