Let x = the number of songs you can buy.
If you use company A at 0.79 dollars per song, your variable is 0.79x. If you use company B at 0.99 dollars per song, your variable is 0.99x. You are going to set both equal to 30.
Company A: 0.79x = 30
Company B: 0.99x = 30
When solving (though I know you didn't ask), do note that you cannot buy part of a song so you would need to round down to the nearest whole number.
So if you use company A, you divide both sides by 0.79 to isolate the variable x and satisfy the division principle of equality:
x = 30/0.79.
Simplify and your answer is 37.97, round down to 37 songs; you'd have 37 songs with company A and 77 cents left over in your account just sitting there because what really can you do with 77 cents on the App Store?
<h2>39/6 = 6.5</h2><h2 /><h2>6 hours 30 minutes</h2>
<h2>Answer:</h2>
x+10y
<h3>Step-by-step explanation:</h3>
3x+2y+(-2x)+8y
First of all you cannot substitute x with y, so what u do u make the numbers with the same letters they have,and I put -2x because + & - equals to -(minus) :-
3x-2x+2y+8y= x+10y
I don't add 1 to x coze when x alone stands for 1, I added +10y because both the y equations had + they were positive so I add a +.
<h3>Hope it helps </h3>
First, set a variable.
Let x = the number of songs bought.
Each song costs 2 dollars. So, we have our first term: 2x.
And there is a fee of 5 dollars for using the website.
2x + 5
And she can't spend any more than 40 dollars. Which means she can spend 40 and under.
So, 2x + 5 ≤ 40 is the answer.
