Question

Evaluate the expression for a=3, b=5, and c=10. (You will get a single number for your answer.)
6a+4b −3c= [what answer}

Show every step.

Answer 1

To evaluate the expression \( 6a + 4b - 3c \) given \( a = 3 \), \( b = 5 \), and \( c = 10 \), we can follow these steps:

1. Substitute the values of \( a \), \( b \), and \( c \) into the expression:

\[
6(3) + 4(5) - 3(10)
\]

2. Calculate each term separately:

- For the first term:
\[
6 \times 3 = 18
\]

- For the second term:
\[
4 \times 5 = 20
\]

- For the third term:
\[
3 \times 10 = 30
\]

3. Now substitute these values back into the expression:

\[
18 + 20 - 30
\]

4. Perform the addition and subtraction from left to right:

- First, add \( 18 \) and \( 20 \):
\[
18 + 20 = 38
\]

- Then subtract \( 30 \) from \( 38 \):
\[
38 - 30 = 8
\]

Therefore, the final result is:

\[
\boxed{8}
\]
