Answer: neither A or B
Step-by-step explanation:
Answer:
x + y = 3 (1)
55x + 40y = 135 (2)
Step-by-step explanation:
Since x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads and the total time for driving is 3 hours,
x + y = 3 (1)
Also, You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads, the distance moved on highways is 55x and the distance moved on the rest of the roads is 40y (since distance = speed × time).
Since the total distance moved is 135 miles, we have
55x + 40y = 135 (2)
So, the system of linear equations that represent the situation is
x + y = 3 (1)
55x + 40y = 135 (2)
Answer:
$707.9941 rounded is $707.99
Step-by-step explanation:
41%=0.41
1199.99*0.41=491.9959
$1199.99-$491.9959=$707.9941
$707.9941 rounded is $707.99
the four doesn't round up so it would just be $707.99.
Hope this helped!
