D
OpenStudy (miastarr):
bc p=parentheses E=exponents m= MULTiply D=division A=add S=subtract so there is no *p* or *e* so you go to *m* wich makes it d
OpenStudy (miastarr):

A.
55 ÷ 11
B.
11 + 16
C.
12 • 3
D.
54 ÷ 3
OpenStudy (miastarr):
p=parentheses E=exponents m= MULTiply D=division A=add S=subtract so its *p* so the answer is D

Okay since it's 10^2 you'll need to do that first since it's PEMDAS
(10^2) ÷ 25 • 20 + 4 ÷ 2 – 14
So 10^2 = 100
It would then be 100 ÷ 25 • 20 + 4 ÷ 2 – 14, next is multiplication so it would be 100 ÷ 500 + 4 ÷ 2 – 14.
Are there answer choices or decimal places?
OpenStudy (miastarr):
its 68
OpenStudy (miastarr):
102
25
(20)+
4
2
−14=68
