6-b/3a, for a =10, b = -9

1 answer

To evaluate the expression 6-b/3a, for a = 10 and b = -9, we substitute the given values into the expression:

6-(-9)/3(10)

Since -(-9) equals 9, the expression becomes:

6 + 9/3(10)

Next, we simplify the expression within the parentheses:

6 + 9/30

To divide 9 by 30, we divide each number by their greatest common divisor, which is 3:

6 + 3/10

Finally, we can add the simplified fractions:

60/10 + 3/10

63/10

Therefore, 6-b/3a, for a = 10 and b = -9, equals 63/10.
