Answer:

Step-by-step explanation:
Add 9 to both sides of the equation, and divide by the coefficient of B.
T = BA -9
T +9 = BA
(T +9)/A = B
We can rewrite that with B on the left:
B = (T +9)/A
Answer:
Step-by-step explanation:
We're given one equation, we have to find the other equation and solve each for 200, and whichever has the lower x is the winner
for Jayden we are given

This looks to be a line. The y values are each separated by a common difference
We can use two points to describe the line

Now we can set both
and
equal to 200
