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?
Answer:
Hey there,
If she is 4.25 feet tall we need to multiply. If the tree is 5.5 times taller we multiply 4.25 by 5.5 which is 23.375 feet tall.
Hope it helped!!!

Answer:
1) B. -2 hours per person
2) C. 3.60 per pound
Step-by-step explanation:
1)
We can make a slope triangle connecting the points (4, 12) and (10,0)
We get -12/6, or -2 as our slope & final answer
2)
You can do x/y to find the unit rate for this one, or in this case 18/5 = 3.6
Originally, you would get 6.56666 repeating as your answer. When you end up rounding, or estimating it, it then becomes just simply 7.
