Evaluate the expression for a=4, b=2, and c=8. (You will get a single number for your answer.)(1 point)

Question

3a−2b +5c=

Answer 1

To evaluate the expression \( 3a - 2b + 5c \) for the given values \( a = 4 \), \( b = 2 \), and \( c = 8 \), we can substitute these values into the expression:

\[ 3(4) - 2(2) + 5(8) \]

Now, calculate each term:

1. \( 3(4) = 12 \)
2. \( -2(2) = -4 \)
3. \( 5(8) = 40 \)

Now combine these results:

\[ 12 - 4 + 40 \]

First, calculate \( 12 - 4 \):

\[ 12 - 4 = 8 \]

Now, add \( 40 \):

\[ 8 + 40 = 48 \]

Thus, the final value of the expression is:

\[ \boxed{48} \]
