For this equation the dog ate 3/4 of the 30 muffins. You would have started with 40 since the dog ate 3/4. So, the dog ate 3/4 muffins, and you would have 10 remaining.

Please let me know if this was right! Thanks!

Find scale factor, solve for x, and solve for y.

snow_tiger [21]

Answer:

Part 1) The scale factor is 3

Part 2) The value of x is 36 in

Part 3) The value of y is 26 in

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

Let

z-----> the scale factor

$z=(10+5)/5=3$

step 2

Find the value of x

To find the value of x, multiply the length of 12 by the scale factor

$x=(12)(3)=36\ in$

step 3

Find the value of y

we know that

$(13)(3)=13+y$

$y=39-13=26\ in$
