Mr. Javier purchased a number of pencils for ₱180 and sold all except 6 at a profit of ₱2 per pencil. With the total amount rece
Luba_88 [7]

Answer:

36 pencils

Cost = 0.2

Step-by-step explanation:

Given

Cost Price = 180

Represent the number of items by x

This implies that the cost of each item is \frac{x}{180}

Selling\ Price = Cost + Profit

Selling\ Price = \frac{x}{180} + 2

Since all but 6 items were sold, the total selling price is:

Total = (x - 6)(\frac{x}{180} + 2)

This amount can be used to buy 30 more items.

So, we have:

(x - 6)(\frac{x}{180} + 2) = x + 30

Multiply both sides by 180

180 * (x - 6)(\frac{x}{180} + 2) =180(x + 30)

(x - 6)(x + 360) = 180x + 5400

Expand brackets

x\² + 360x - 6x - 2160 = 180x + 5400

x\² + 354x - 2160 = 180x + 5400

Equate to 0

x\² + 354x - 180x - 2160 - 5400 = 0

x\² + 174x - 7560 = 0

Expand

x\² + 210x - 36x - 7560 = 0

x(x + 210) - 36(x + 210) = 0

(x - 36)(x + 210) = 0

x - 36 = 0 or x + 210 = 0

x = 36 or x = -210

<em>Since, number of items can't be negative, we have to discard x = -210.</em>

Hence:

x = 36

<em>We can then conclude that, Mr. Javier purchased 36 pencils</em>

Recall that

Cost = \frac{x}{180}

Cost = \frac{36}{180}

Cost = 0.2

Will mark brainlist please help geometry
MrRissso [65]

9514 1404 393

Answer:

   ΔPRQ ≅ ΔVWX

Step-by-step explanation:

ASA means the corresponding side lies between the two corresponding angles. That is true for triangles PRQ and VWX.

We chose to name the triangles starting with the angle marked with the single arc, then the angle marked with the double arc. They can be named using any permutation of the letters, provided that the same correspondence is achieved between the two names.
