Answer:
Option B is correct.
The property of equality that justifies the following statement is; Subtraction property.
Step-by-step explanation:
Subtraction property of equality states that you subtract the same number from both sides of an equation.
i.e, if a=b then, a-c=b -c
Given the statement:
if p =q
then, by definition of subtraction Property
Subtract r from both sides of an equation we get,

Therefore, the property of equality that justifies the following statement is; Subtraction property.
27 because 4*4=16. 65+16=81 and 81 divided by 3=27
3.4 is the answer (rounded up of course)
If you knew that 8*300=2400
Then you could likely figure that 8*20=160
And then just add the two together to get 2560
