Answer:
y=-7
x=3
Step-by-step explanation:
I just used a calculator. Hope this helps. :)
Beth purchased $21.25 worth of groceries. The sales tax rate is 7.5%. What was her total bill?
The tax is calculated by 0.075 * 21.25 = 1.59375 or $1.59. So the total bill is the cost of items purchased plus tax, which is $21.25 + $1.59 = $22.84.
Back to your question:
What is the total cost of a sweatshirt if the regular price is $45 and the sales tax 5.75%
The tax is calculated by 0.0575 * 45 = 2.5875 or $2.59. So the total bill is the cost of items purchased plus tax, which is $45 + $2.59 = $47.59
Hope this helped! Good luck!

I think most of the time it might be bots or the person might not know the answer and simply want the points, if you have a question I can take a look at it though.
Answer: £2530.64
Step-by-step explanation:
The formula for calculating amount is given as :
A = P
Where :
A = amount
P = principal
r = rate%
n = number of years
Substituting the values of each into the equation we have
A = 2000
A = 2000 (
)
A = 2530.638037
A ≈ £2530.64
Answer: x = { 2 ; 3 }
+) x² - 3 = x² - 1 - 2 = (x - 1)(x + 1) - 2
+) x² - 3 is divisible by x-1 but (x -1)(x + 1) is divisible by x-1
=> 2 must be divisible by x-1
=> x - 1 is divisor of 2
=> (x - 1) ∈ {-1; 1; 2; - 2;}
but x > 1 => x - 1 > 0
⇒ x - 1 = {1; 2; }
+) with x - 1 = 1 => x = 2
x - 1 = 2 => x = 3
