Answer:
Step-by-step explanation:
two birthday gifts n each costs $12.50 so 12.50x2 = $25
sales tax was 6.75% on $25 = 25x6.75/100 = $1.69
total cost including tax = 25+1.69 = $26.69

Option: D is the correct answer.
The property which is illustrated by the given statement is:
D. Identity Property of Addition
<h2>
Step-by-step explanation:</h2>
We know that an identity is a value which when added to any element of the set gives the resultant as the element itself.
Also, we know that the identity under addition is always: zero.
Because when zero is added to any number then the resultant is the number itself i.e. adding zero does not affect the value.
Hence, by the Identity Property of Addition we have:
0 + x = x
The answer is 10:40
so 1:4
add it up
1+4=5
so 5 total units
$50=5 units
divide by 5
$10=1 unit
so 1:4=10:10 times 4=10:40
the answer is 10:40
(4x - 3)(2x - 1) ≥ 0
First, find the zeros:
4x - 3 = 0 2x - 1 = 0
x = 
x = 
Next, plot these points and choose test points on the outside and between the zeros:
←-------0------------
------------1------→
Lastly, plug in the test points and look for a positive result (since it is greater than 0).
Test Point 0: [4(0) - 3][2(0) - 1] = ( - )( - ) = + THIS WORKS!
Test Point : [4() - 3][2() - 1] = ( - )( + ) = - <em>This does NOT work</em>
Test Point 1: [4(1) - 3][2(1) - 1] = ( + )( + ) = + THIS WORKS!
Answer: x ≤ or x ≥
Interval Notation: (-∞, ] U [, ∞)
