Evaluate the expression for the given value of the variable(s).
2 answers:
The given expression is 5a+5b The given values of a and b are a=-6 ,b=-5
Substituting the values of a and b in the expression we have :
5a+5b= 5(-6)+5(-5)
= -30 -25 ( when a positive and a negative number is multiplied the result is a negative number)
-30-25=-55 (same signs are added)
The answer to the expression 5a+5b when a=-6 anf b=5 is -55.
[The given options are not correct.]
The answer to what you have there is -55 using order of operations. 5 times -6 is -30. 5 times -5 is -25. add. You get -55.
