14x45=630
43×2=86
(14×45)-(43×2)= 630-86=544
there would be 544 pens left
X=31, the other post justifies, I just wanted to make it more accessible for if someone just needs the answer :)
<h2>Answer </h2>
D. 6x>_360; x>_60
<h2>Explanation</h2>
Let
be amount you will save each weeks
Since we know that you are saving over a period of 6 weeks, you will save
.
We also now that your goal is to save at least $360.00 over the period of 6 weeks, so saving more than $360.00 will be very desirable, but the goal is to save $360.00. We can rephrase this as: You need to save $360.00 or more; we can say the same using the inequality symbol
(greater on equal than)
Now we can combine our tow parts using the inequality symbol:

To simplify divide both sides by 6:


You need to save at least $60 per week, so the correct answer is D. 6x>_360; x>_60
Answer:
therefore the side of the square is 2x + 5.
Step-by-step explanation:
i) let the side of the square be a
ii) therefore the perimeter of the square = 4a
iii) therefore 4a = 8x + 20
iv) therefore a = 2x + 5
therefore the side of the square is 2x + 5.
