Answer:
(-1, -5)
Step-by-step explanation:
1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)
Part A:
Given that Rachel is planning a wedding for 100 to 250 people, the <span>inequality in terms of p people that describes how many people Rachel plans to invite is given by:
100 ≤ p ≤ 250
Part B:
Given that the </span>caterer charges $20 per person, plus a flat fee of $200,<span> the </span><span>inequality that shows how much the caterer will charge in terms of p is given by:
20(100) + 200 ≤ 20p + 200 ≤ 20(250) + 200
</span>
Part C:
<span>The range of catering fees (C) that Rachel is considering is given by:
</span><span>20(100) + 200 ≤ 20p + 200 ≤ 20(250) + 200
2000 + 200 ≤ C ≤ 5000 + 200
2200 ≤ C ≤ 5200
Therefore, the range of catering fees Racheal is considering is from $2,200 to $5,200

Since you are solving for S, you need to single it out. Do this by adding 3 to both sides which eliminates the -3 and adds 3 to -5 giving you -2. Now S = -2
<u>Answer:</u>
If the spool has 10 cm of circumference or perimeter, this means that 10 cm of thread fits the whole circumference of the spool, which also means that
<h2>
1 unwind is equivalent to 10 cm of thread.
</h2>
Then, we have to make the following question:
If 10 cm of thread is equivalent to 1 unwind, to how many unwinds is equivalent 80 cm of thread?
If we want to know how many time does Alex need to unwind the spool, we can use the following relation also called the <u>Rule of Three:
</u>
<u>
</u>
The answer is:
Alex must unwind the spool 8 times in order to get 
cm of thread
