Answer:
2x + 11 = 20
Step-by-step explanation:
let's start by assigning the variable x to certain number
, if we two times a certain number we got 2x, and if we added to 11 the result is 20. So, ordering the equation we will obtain:
2x + 11 = 20
1/2 of the time
d=st
distance=speed times time
we want to find time
divide both sides by speed
d/s=t
d=20
s=40
20/40=t
1/2=t
this is in hours
she drove for 1/2 hour or 30 mins
Answer:
C
Step-by-step explanation:
