Answer:

Step-by-step explanation:
We have a separable equation, first let's rewrite the equation as:

But:

So:

Multiplying both sides by dx and dividing both sides by 3a+y:

Integrating both sides:

Evaluating the integrals:

Where C1 is an arbitrary constant.
Solving for y:


So:

Finally, let's evaluate the initial condition in order to find C1:

Solving for C1:

Therefore:

Answer:
So we have this equation:
r/10 + 4 = 5
FIrst, we can substract 4 in both sides
r/10 + 4 - 4 = 5 - 4
r/10 = 1
Now, we can multiply both sides per 10:
r/10 * 10 = 1 * 10
r = 10
And we know that r = 10, and that's the result of the equation.
First the distributive property actually means "to share"
Second here's how you do it ...
the two numerators are multiplied , same with the denominator
4 x 10 and 25 x 1
this gets you 40/25 as an improper fraction but here is the simplified answer
1 3/5
