To evaluate the expression \( 3|a| + 5|b| \) given \( a = -2 \) and \( b = -1 \), we first find the absolute values of \( a \) and \( b \):
\[
|a| = |-2| = 2
\]
\[
|b| = |-1| = 1
\]
Next, we substitute these values into the expression:
\[
3|a| + 5|b| = 3(2) + 5(1)
\]
Now, we perform the multiplication:
\[
3(2) = 6
\]
\[
5(1) = 5
\]
Finally, we add these results together:
\[
6 + 5 = 11
\]
Thus, the value of \( 3|a| + 5|b| \) is \( \boxed{11} \).
\[
|a| = |-2| = 2
\]
\[
|b| = |-1| = 1
\]
Next, we substitute these values into the expression:
\[
3|a| + 5|b| = 3(2) + 5(1)
\]
Now, we perform the multiplication:
\[
3(2) = 6
\]
\[
5(1) = 5
\]
Finally, we add these results together:
\[
6 + 5 = 11
\]
Thus, the value of \( 3|a| + 5|b| \) is \( \boxed{11} \).
