Answer:
x3-20
Step-by-step explanation:
x stands for the month 3 is the money that she is spending each month if you multiply those together you get the amount of money she has spent over x amount of months minus the 20 dollars on her gift card
Simplify
f(x) = 3 + 11
Multiple
fx = 3x + 11
<span>Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = 11x-1 + 3
Simplifying
f = 11x-1 + 3
Reorder the terms:
f = 3 + 11x<span>-1</span></span>
Answer:
t = 
-------------(1)
The value of t is, 
hour
Step-by-step explanation:
The 1st train travels at 
mph whereas the 2nd train travels at
mph. The trains are headed towards each other. They are s miles apart. In 1 hour their distance is reduced by 
mile
So, in t hour their distance is reduced by 
mile.
Now if the two trains meet after t hour of starting, then,
⇒ t = -------------(1)
If s = 250 unit, = 60 unit and, = 40 unit , then,
from (1), t = (250/(60 + 40)) hour = hour ----(2)
