At the start of school year, Mario stocked up on school supplies, which included lined filler paper and number two wood pencils.
Hitman42 [59]
Let X be the price for a pack of paper 

<span>Let Y be the price for a box of pencils. </span>

<span>1) X * 3 packs + Y * 3 boxes = $3.25 </span>

<span>2) X * 2 packs + Y * 1 box = $2.00 </span>

<span>Re-arranging equation 2) gives you Y = ($2.00 - X * 2 packs) / 1 box </span>

<span>Subsitute Y for the Y term in equation X. Multiply through the bracket, collect like terms and solve for X. Then you can use either equation to solve for Y (if you don't get the same answer, you've made a mistake).</span>

Triangle ABC is similar to DEF.
Schach [20]

Answer:

Step-by-step explanation:

Answer:

1. The scale factor here is 1.5

2. The scale factor here is 2/3

Step-by-step explanation:

Here, we shall be dealing with scales of triangles.

we have two triangles;

ABC and DEF

longest sides are in the ratio;

12 : 8

1. What scale factor translates DEF to ABC?

The ratio of the length can be beaten down to 3:2

So therefore, we can see that by multiplying the sides of of DEF by 1.5, we can arrive at the sides of ABC

So the scale factor here is 1.5

2. This is like the other way round of what we have above.

By multiplying the sides of ABC by 2/3, we shall have the sides of DEF
