Answer:
A. 201.6 = 11.2f
Step-by-step explanation:
we solve for each unknown to verify which equality will require the division property:
#A. 201.6 = 11.2f

Hence, division property used.
#B. 35.4=Z ÷ 3.1

Hence, multiplication property used.
#C. t/3.2=15.1

Hence, multiplication property used.
#D. 201.6 = 11.2+c

Hence, subtractionproperty used.
The answer is 14.
(7x+25)+(3x+15)=180
x=14
x = -3
So to figure this out we can readjust the equation to make it easier to solve
is equal to 
From here we can just subtract 9 from both sides and we get our answer!

3.2x + 5.1x = 41.5
- add 3.2x and 5.1x
8.3x = 41.5
- divide both sides by 8.3
x = 5
