Answer:
The answers of the proof are the following:
2. Division Property of Equality
3. x+ 1 = -4
4. Subraction Property of Equality
5. x = -5
-12+-12=-24
-6+-6=-12
-11+-11=-22
-10+-10=-20
-9+-9=-18
-8+-8=-16
-7+-7=-14
-5+-5=-10
-4+-4=-8
-3+-3=-6
-1+-1=-2
1+1=2
2+2=4
3+3=6
4+4=8
5+5=10
6+6=12
The first thing we must do for this case is find the scale factor.
We have then that for the larger side of both triangle, the scale factor is:

To find the other two sides, we must apply the scale factor on each side of the triangle FGH.
We have then:
For PQ
For QR
Answer:
You have that the lengths for the other two sides of triangle PQR are:
Milk (m) , butter (b)
m + b = 70.4
b = 30.6
m + 30.6 = 70.4
m = 70.4 - 30.6
m = 39.8 mL of milk are needed
