Answer:
D. 1.06(3.19x + 1.20y + 1.20z)
Step-by-step explanation:
Since marker packs are 3.19 each, the cost of the marker packs she buys can be represented by 3.19x.
All spiral notebooks are 1.20 each, so the cost of the wide ruled notebooks can be represented by 1.20y.
The cost of the college ruled notebooks can be represented by 1.20z.
In the expression, all of these terms have to be added together and multiplied by 1.06 to calculate the sales tax.
So, the expression will be 1.06(3.19x + 1.20y + 1.20z)
D is the correct answer

Answer:
The solution is x = 3
Step-by-step explanation:
Hi there!
First, let´s write the equation:
log(3) + 2 log(x) = log(27)
Substract log(3) from both sides of the equation
2 log(x) = log(27) - log(3)
Apply logarithm property: log(a) -log(b) = log(a/b)
2 log(x) = log(27/3)
2 log(x) = log(9)
Apply logarithm property: log(xᵃ) = a log(x)
log(x²) = log(9)
Apply logarithm equality rule: if log(a) = log(b) then a = b
x² = 9
Apply square root to both sides of the equation
x = 3
The solution is x = 3
Have a nice day!
