For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
the equation that will help find the time it takes chelsea to get to school on the bus is:
45 * t = 2.5 * (1-t)
Note: the equation will have one solution.
9a-5x
step by step explanation:
you can only add and subtract numbers that have the same variables.
12a and 3a are related because there variable is both a.
when u subtract 12a-3a you get the answer of 9a using subtraction.
7x and -2x are the second pair of related terms because they also have the same variable (x)
7x-2x is 5x using subtraction.
put the expression together:
9a-5x
hope this helps!
