Did you ever get the answer
a = The cost of the pizza.
b = The cost of the pizza and sales tax.
f(a) = The cost of the pizza.
g(b) = The cost of the pizza and sales tax.
g(f(a)) = The cost of the pizza, sales tax, and delivery fee
$3.00 x .05 = 15 cents
$3.00+ .15= $3.15
3.15 final answer
we know that
Additive identity property:
If we add a real number to zero or add zero to a real number, then we get the same real number back.
The number zero is known as the identity element, or the additive identity.
For example: a+0 =a
we can see that adding gives same result
so, 0 is the additive identity here
Hence , option-B........Answer
Answer:
42
Explanation:
Using Order of Operations, we have to evaluate the exponent first:
27 + 6(2 + 3/6)
Simplifying the fraction, we have:
27 + 6(2 + 0.5)
Add the values inside the parenthesis:
27 + 6(2.5)
Multiply:
27 + 15
Add:
42
