A music player was marked down by 1/4 of the original price.
shepuryov [24]

Answer:

Step-by-step explanation:

marked down by 1/4 of the original price.

let x represent original price

original price - 1/4 of original price = sales price

x - 1/4x = 128

4/4x - 1/4x = 128

3/4x = 128

x = 128/(3/4)

x = 128 * 4/3

x = 512/3

x = 170.666 rounds to 170.67 <== original price

==============================

I hope I am understanding this one correctly...

let x = price the store paid

x + 1/2x = 170.67

2/2x + 1/2x = 170.67

3/2x = 170.67

x = 170.67 / (3/2)

x = 170.67 * 2/3

x = 341.34/3

x = 113.78 <=== what the store paid

===========================

the difference between the discount price..I am assuming this is the $ 128 from part A.....and what the store paid....113.78...from part B..

128 - 113.78 = $ 14.22 <==

I am not completely sure about B and C......B confused me.....and if B is wrong, so is C.

Find cosX and cosZ. Write each answer as a fraction and as a decimal. Round to four decimals places, if necessary. Fractions to
JulsSmile [24]

Answer/Step-by-step explanation:

Recall the acronym, SOHCAHTOA.

✔️Cos X = adj/hyp (CAH)

Adj = 10

Hyp = 26

Cos X = 10/26

Simplify

Cos X = 5/13 (as a fraction)

Cos X = 0.3846 (as a decimal to 4 d.p)

✔️Cos Z = adj/hyp (CAH)

Adj = 24

Hyp = 26

Cos Z = 24/26

Cos Z = 12/13 (as a fraction)

Cos Z = 0.9231 (as a decimal to 4 d.p)

First you had to add by seven from both sides of equation form.

-7+\frac{f}{2}+7=-1+7

Then simplify by equation.

\frac{f}{2}=6

Next, you multiply by two from both sides of equation form.

\frac{2f}{2}=6*2

And finally, simplify by equation.

6*2=12

2*6=12

12/6=2

12/2=6

f=12

Final answer: \boxed{f=12}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

to "show work" just plug in each x value into that equation. you will never learn if all you do is copy down answers. i have given you all of the correct answers, and all you need to do is plug in the values for each x value into the equation, multiply then add. good luck man.
