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)
= -30 + (-25)
= -55
Therefore, when a = -6 and b = -5, 5a + 5b = -55.
To evaluate the expression 5a + 5b, we substitute the values of a and b into the expression.
Given that a = -6 and b = -5, we have:
5(-6) + 5(-5)
Now, we simplify the expression using the order of operations (BIDMAS/PEMDAS):
= -30 + (-25)
= -30 - 25
= -55
Therefore, the value of the expression 5a + 5b when a = -6 and b = -5 is -55.
