Answer:
No, They are not equivalent
Step-by-step explanation:
The two expressions are only said to be equivalent if they are the same regardless of whatever value the variable(s) is.
The variable in this question is x.
To prove this, we equate both expressions:


This shows that they have the same value ONLY when x is 1.
This is why Andre says that they are equivalent, but they are not.
Answer: 9.3d−g-10.4f
Step-by-step explanation:
Let us assume the gas bill of Paul in February = x dollars
Then
Electric bill of Paul for the month of February = (x/2) + 3
Amount of Electricity bill of Paul for the month of February = $92
then we can write the equation as
(x/2) + 3 = 92
x/2 = 92 - 3
x/2 = 89
x = 89 * 2
= 178 dollars
So the gas bill of Paul in February is $178. I hope this is the answer you were looking for.
A rate is common.
Lets find something that isn't constant.
The speed a runner can't be constant
Perhaps they run for 1 hour and get 1 mile done, and the other hour, they run 1.3 miles in 1 hour.
