<h3>Answer:  25w+200 > 750</h3>

==========================================================

Explanation:

He starts off with 200 cards. Then he adds on 25w more cards for each week (w). Overall, he'll have 200+25w cards

We can think of it like this:

  • After 1 week, he adds on 25*1 = 25 cards
  • After 2 weeks, he adds on 25*2 = 50 cards total
  • After 3 weeks, he adds on 25*3 = 75 cards total
  • After 4 weeks, he adds on 25*4 = 100 cards total, and so on.
  • After w weeks, he adds on 25w cards total

So that's another way to see where the 25w comes from.

The expression 200+25w is the same as 25w+200. This is because we can add two numbers in any order.

------------

Since he wants to know when he'll have more than 750 cards, this means we set 25w+200 greater than 750.

That's how we get to the answer of 25w+200 > 750

Notice how there isn't a line under the inequality sign. We aren't using the "greater than or equal to" symbol here. We want to know when the cards gets over 750, but we don't want to know when it's equal to 750.

10 points. Please help me with numbers 9-13.<br> Numbers 9-13 is the picture.

Answer:

x  = 18

y = 15

Step-by-step explanation:

Remark

Step One

The main step is to realize that if the lower left hand angle is 90 degrees, then the upper left hand angle is also 90. That is because the interior angles of parallel lines are supplementary. If one of the angle is 90 degrees, so is the other.

<em><u>Conclusion from the Remark</u></em>

5x = 90

x = 90/5

x = 18 degrees

Step Two

Find y

y is just a bit harder to find . The safest way is to add all four interior angles together. For any trap*zoid (you cannot spell this word properly. The editor has a fit), the interior angles add up to 360 degrees.

So just add the 4 angles together and equate to 360

5(y + 11) + 4y  - 10 + 90 + 90 = 360     Combine like terms

5(y + 11) + 4y -  10 + 180 = 360            Combine again

5(y + 11) + 4y + 170 = 360                   Subtract 170 from both sides

5(y + 11) + 4y = 360 - 170                     Combine like terms

5(y + 11) + 4y = 190                             Remove the brackets

5y + 55 + y4 = 190                             Combine like terms

9y + 55 = 190                                     Subtract 55 from both sides.

9y = 190 - 55

9y = 135                                              Divide by 9

y = 135 / 9

y = 15
