Show all steps evaluate the expression for the given value of the variable 5a+5b,a=-6,b=-5thanks
What is 5(-6) + 5(-5) ?
5a+5b
5(6)+5(5)
30+25
55.
To evaluate the expression 5a + 5b when a = -6 and b = -5, follow these steps:
Step 1: Substitute the given values for a and b into the expression:
5(-6) + 5(-5)
Step 2: Simplify the expression using multiplication:
-30 + (-25)
Step 3: Simplify further by adding the two terms:
-30 - 25
Step 4: Perform the subtraction:
= -55
