Answer:
A
Step-by-step explanation:
<em>Okay so, im not the best at explaining, but so we have a percentage. its 25%. you want to take the 25% and put it over 100 because a percentage is a number or ratio expressed as a fraction of 100. so it will be written as 25%/100</em>
<em />
<em>divide 25 by 100 and you get 0.25, correct? so that's one step further towards the answer.</em>
<em>then we write x/90 because we don't know (well we do) what we're gonna put. but, we're gonna multiply 0.25 by 90 and we get 22.5, which is equivalent to </em><em>22.50</em><em>.</em>
No . but she can buy 2 of the books but not all 3
There are many different types of equations we can use to allow x to equal 19! Below are some examples :) See if you can come up with some on your own based off of these examples:
5x = 95.....................................Divide both sides b 5
x = 19.......................................There's one for you :)
_____________________________________________________________
1 + x - 5 = 15............................Combine like terms
x - 4 = 15..................................Add 4 to both sides
x = 19
_____________________________________________________________
There's just a couple of examples, but see if you can come up with some on your own and let me know if you get stuck!
Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you any further! :D
Answer:
