Use PEMDAS
20 * 20/5 + 100 - 50
Multiply and divide first
20 * 20 = 400
400/5 = 80
Add 100 and then subtract 50
80 + 100 = 180
180 - 50 = 130
130 is the answer.

Answer:
A and C
Step-by-step explanation:
By letting x = 0 she is eliminating the terms in x , rather than simplifying
A
9x - 3x - 4 ← collect like terms
= 6x - 4
B
12x - 4 ← already in simplest form
C
5x + x - 4 ← collect like terms
= 6x - 4
Thus A and C are equivalent expressions
