Evaluate the expression for the given value of the variable(s).
5a + 5b; a=−6, b=−5
To evaluate the expression 5a + 5b when a = -6 and b = -5, substitute the values of a and b into the expression.
5(-6) + 5(-5)
This simplifies to:
-30 + (-25)
Combining like terms, we get:
-30 - 25
Which equals:
-55
So the value of the expression is -55.
To evaluate the expression 5a + 5b when a = -6 and b = -5, substitute the values of a and b into the expression:
5(-6) + 5(-5)
Then, simplify the expression:
-30 - 25
Finally, perform the subtraction:
-55
Therefore, when a = -6 and b = -5, the expression 5a + 5b evaluates to -55.
