Answer:
-6+x
Step-by-step explanation:
Let the number=n
x-n=6
-n=6-x
n=-6+x
Answer:
not sure
Step-by-step explanation:
So car A travels Distance = 60 km/hr*(1+x)
Car B travels Distance = 75 km/hr(x)
Where x is the time in hours.
Those two equations are equal when on overtakes the other
so:
60 +60x = 75x
60=15x
x=4, but my expression is written to count from when car B commenced travel. So total time is 5 hours from the car A setting off.
Apply the negative exponent rule, so move the expression to the denominator to make the exponents positive.
Your answer is:
