The expressions are not equivalent because if you simplify Expression 2, it simplifies to 5x
5x is not equal to 3 - 5x
A is your answer! Because of how many sides it has.
Answer:
B
Step-by-step explanation:
The number
is 8 times greater than 
thus, 
multiply both sides by 
we get 
if we take a = 2.5 and b = 3.1 we get 2.5/3.1 = 0.8
then B is the answer
1 day = d
0 + 3d = 4 + 2d
3d = 4 + 2d
d = 4
It'll take 4 days
Hope this helps ^-^
