False, they already have that as a rule in the order of operations. That’s what PEMDAS stands for. The E stands for Exponents.
Answer:
1)
2x = 16
16 ÷ 2 = 8
x = 8
2)
2 + x = 28
28 - 2 = 26
x = 26
3)
3 ÷ 6 = 0.5 (I'm not sure about this one)
4)
27 - 10 = y
27 - 10 = 17
y = 17
5)
1/3 = 400 cal
400 + 400 + 400 = 1, 200
whole pizza = 1,200 calories
6)
$287 - $175 = $112
