2 answers:
Answer:
Step 1:
Let x represent the amount of each friend donate
Website keeps = 5%
Total funding I receive = $ 47.50
4.75x = $47.50
Step 2:
4.75 = $47.50 - <em>Write the equation</em>
=
-<em> Divide both sides of the equation by 4.75</em>
<em>The solution is x = 10</em>
ANSWER: Each friend donates $10
<em>hope this helps Have a good day.</em>

Answer:
9. ±1, ±2, ±3, ±6
11. ±1, ±2, ±3, ±4, ±6, ±12
Step-by-step explanation:
The possible rational roots are (plus or minus) the divisors of the constant term, divided by the divisors of the leading coefficient.
Here, the leading coefficient is 1 in each case, so the possible rational roots are plus or minus a divisor of the constant term.
