Answer:
B: x = -12
Step-by-step explanation:
12 - (3 × 2)^2 + 4 × 3
Use PEMDAS, meaning solve what's in the parentheses first (P stands for parentheses)
12 - (6)^2 + 4 × 3
We get 6 because 3 × 2 = 6
Next step is solve any exponents (E for exponents)
12 - 36 + 4 × 3
We get 36 because 6 × 6 = 36 (the exponent was 2 meaning multiply the same number, 6, twice: 6 × 6)
Now we move on to multiplication and division (M for multiplication and D for division)
These are interchangable in that either can go first depending on its location in the equation
However, since there is no division in this problem we automatically skip to multiplication
12 - 36 + 12
We answered 12 because 4 × 3 = 12
Our last steps in PEMDAS are addition and subtraction (A for addition and S for subtraction)
These are also interchangable, but both are apparent in this problem
Now it depends on location
Whichever sign (addition or subtraction) is first in accordance from left to right is where we start first)
Subtraction is first
-24 + 12
Now we add -24 + 12
-12
Selling price of a pack of cinnamon scented pencils = $8
Cost of the pack of pencils along with tax = $8.64
Then
Amount of tax taken = (8.64 - 8.00) dollars
= 0.64 dollars
Percentage of sales tax taken = (0.64/8.00) * 100
= 64/8
= 8 percent
So the rate of sales tax for the pack of cinnamon scented pencils is 8%. I hope the procedure is clear enough for you to understand. You can use this method for solving similar problems without requiring any help from outside.
