Answer:
Step-by-step explanation:
If the jacket was discounted at 25%, that means that you get 25% off, right? What it also means is that you are still paying 75%. To get to the price of the jacket on sale, multiply the price of the jacket by 75% (as a decimal):
290(.75) = 217.50
That's the price of the jacket when it is 25% off the original price. If Arianna got an additional 10% off that price, that means she got 10% off but is still paying 90%. To get to the final price that she paid, multiply the sale price of the jacket by 90% (as a decimal):
217.50(.90) = 195.75
That's what she paid in the end for the jacket (i guess not counting tax...?)
Hey there!
“What is the best decimal equivalent to 3 9/100?”
3(100) + 9
3(100) = 300
300 + 9 = 309 ⬅️ solving for your numerator
100 ÷ 1 = 100 ⬅️ solving for your denominator
309 / 100 ➡️ 309 ÷ 100 = 3.09
Thus your answer is: 3.09 ☑️
Good luck on your assignment and enjoy your day!

Answer:
x = -1
Step-by-step explanation:
The usual approach to these is to square the radicals until they are gone.
Each time the equation is squared, the possibility of an extraneous root is introduced. Here, x=3 is extraneous: it does not satisfy the original equation.
The solution is x = -1.
_____
Using a graphing calculator to solve the original equation can avoid extraneous solutions. The attachment shows only the solution x = -1. Rather than use f(x) = 2, we have rewritten the equation to f(x)-2 = 0. The graphing calculator is really good at showing the function values at the x-intercepts.
