Answer:
r=s+5
Step-by-step explanation:
So, letsgo over what we know:
The regular price is r
The sale price is s
Now lets compare the difference between r and s:
10r = 5s
20r = 15s
30r = 25s
What is the difference between the r and s value in each situration?
Well, from what I can see, r is always 5 more than s.
This can be writen as:
r = s+5\
So this is our equation, for if you plug in any number for s, you will get an accurate r value.
For instance, if you say s is 25:
r=25+5
=
r=30
This looks just like the 30r=25s in the table above.
So:
r=s+5
Hope this helps! :)

Answer:
YZ ≅ AB
Step-by-step explanation:
A translation is a correspondence between two mathematical figures, for instance, the coordinates of each point in a straight line of one figure that is added to the coordinates of the corresponding point on the other figure.
But here, we are given a Δ XYZ which is translated to ΔCAB. This tells us more about how the corresponding points preserve their congruence nature.
i.e.
X corresponds to C
Y corresponds to A
Z corresponds to B
Similarly;
XY corresponds to CA
YZ corresponds to AB
XZ corresponds to CB
Since both triangles preserve their congruence nature, then all corresponding points are congruent as well.
Therefore, from the choice of options given, only YZ corresponds to AB is the right answer.
i.e.
YZ ≅ AB
Answer:
37.5%
Step-by-step explanation:
1/8 is 12.5% so multiply 12.5 x 3.
