P=100a÷t solve for a
2 answers:
<u><em>a=1/100pt is the correct answer.</em></u> First you had to multiply by t from both sides of equation, and it gave us, ⇒ . And then you had to flip an equation, and it gave us, ⇒
. You can also divide by one-hundred (100) from both sides of equation, and it gave us,
. And finally, and it gave us the answer is a=1/100pt is the final answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

Let a and c represent, respectively, the price of an adult and a child ticket. We know that
Multiply the first equation by 3 and the second equation by 2 to get
Subtract the two equations to have
Plug this value in the first equation to get
Your formula for this is 
and 
. Get everything on one side of the equals sign, set it equal to 0 and factor. When you do this you get (x-3)(x+27). The Zero Product Property rule tells us that either x-3 = 0 or x+27 = 0 and that x = 3 and -27. The only thing in math that will NEVER be negative besides time is distance/length, therefore, x cannot be 27 and has to be 3.
