Answer:
Step-by-step explanation:
We have the equation
with the initial condition
. It is not difficult to notice that this is a linear equation, which has the general expression
.
The solution of this equation is expressed by a general formula:
.
In the particular case of our equation, we have

.
Then, we must calculate the integrals
that implies
,
and

Then,
.
In order to obtain the value of the constant we substitute the initial condition
that implies 
Therefore,
.
Answer: Yes they could be simiualr
Step-by-step explanation:
one is just bigger than the other
172 = 1/2 * x + 45
172 = 1/2x + 45 / - 45 (both sides)
127 = 1/2x / * 2 (both sides)
x = 254
