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?
First one is 40 cube square and the second one is 125 cube square.
Answer:
12 ≤ x - 7
Step-by-step explanation:
let "x" represent the number
The term decreased means subtraction.
The problem indicates that 12 cannot be greater than a number decreased by 7. Use ≤ which means less than or equal to.
≤ less than or equal to 12 means that 12 is the maximum value.
Inequalities are just like equations it's just that the sign flips anytime you multipliy or divide by a negative number
1.
First Add 7 to both sides
2.
First Subtract 12 From Both Sides
Answer:
C
Step-by-step explanation:
If you divide the money he payed for the 4 bagels (5 divided by 4),
You would get $1.25 for each bagel.
If B represents the number of bagels, it would be
C : 1.25b
