Question

P=m/1+rt solve for t

Answer 1

I assume you mean:

P=m/(1+rt)  multiply both sides by (1+rt)

P(1+rt)=m  perform indicated multiplication on left side

P+Prt=m  subtract P from both sides

Prt=m-P  divide both sides by Pr

t=(m-P)/(Pr)

Answer 2

Hello there! Thank you for asking your question here at Brainly. I will be assisting you with answering this question, and will teach you how to handle it on your own in the future.

(1) First, let's take a look at what we're dealing with.

We have an equation; 
P = m/1 + rt, solve for t.

(2) Understand the problem, and know how to handle it.

Since we're solving for t, we need to isolate t by performing the opposite order of operations on the side that t is on.

(3) Take action once procedures (1) and (2) are understood/done.

P = m/1 + rt
We can get rid of the "1" in the equation, as multiplying anything by 1 does nothing.
Now we have:
P = m + rt

Now, we need to subtract m from both sides to isolate rt.

P - m = rt
Now to solve for t and the problem overall, we need to divide both sides by r.
$\frac{P - m}{r}$ = t

Your final solution for t is:

t = $\frac{P - m}{r}$

Remember your 3 steps:
(1) Examine what you're dealing with.
(2) Understand the problem that's been given to you, and how to handle it.
(3) Apply the proper steps to come to your solution.

I hope this helps!
