Answer:
n=2
Step-by-step explanation:
Simplify.
6−3(n−2)=8−n
6+(−3)(n)+(−3)(−2)=8+−n(Distribute)
6+−3n+6=8+−n
(−3n)+(6+6)=−n+8(Combine Like Terms)
−3n+12=−n+8
−3n+12=−n+8
Add n to both sides.
−3n+12+n=−n+8+n
−2n+12=8
Subtract 12 from both sides.
−2n+12−12=8−12
−2n=−4
Divide both sides by -2.
-2n/-2 = -4/-2
n=2
Answer:
Step-by-step explanation:
Because we are looking for the scale factor of the model to the bridge (model first), the scale factor will be less than one.
Each fraction (
) can be simplified to . Therefore, the scale factor of the model to the bridge is .
Let n be Fritzs' car speed, and n+12 be the speed of the train. Then:
1/2 (n)=1/3 (n+12)
2n+24=3n
n=24 mph
n+12=36 mph
Fritz travels 12 miles to work.
30 min @24mph=12 miles
20 min @36mph=12 miles
