Answer:
Identity property
Step-by-step explanation: because the product of any number and one is that number
Answer:
23833.41cm²
Step-by-step explanation:
A=πr2=π·87.12≈23833.40992cm²
That rounds up to 23833.41cm²
Answer:
A.
Step-by-step explanation:
The expression (1/4) * d + 7 really just means "one-fourth times d, plus 7"
Option A says the same expression, as we know that the product means multiplication, and that we add 7 at the end. For this reason, it is the correct response.
I hope this helps!
1- multiply bottom equation by -3
3x+3y=27
-3x+111= 33
111+3y=60
3y=60-111
3y= -51
y= -17
Replace y in first equation with -17
3x+3(-17)= 27
3x-51=27
3x=27+51
x=26
Here, rest of them in the pic..
K=1/2 is the correct answer.
