Answer:
x = 15/7
Step-by-step explanation:
Combine x terms together.
-7x + 9 + 10 = 4
Now add 9 and 10 to get 19.
-7x + 19 = 4
Subtract 19 from both sides.
-7x = -15
Divide -7.
x = 15/7
Answer:
Step-by-step explanation:
The scenario is illustrated in the attached photo.
Desiree drove north for 30 minutes at 50 miles per hour.
Distance = speed × time
Distance travelled by Desiree to the north is 50 × 30 = 1500 miles
Distance travelled by Desiree back from the north and to the south is
60 × 20 = 1500 miles
She started from south and drove 1500 miles towards the north. She returned by driving 1200 miles again towards south . Distance of Desiree from where she started will be 1500 - 1200 = 300 miles.
She is 300 miles from her starting position and she is in the southern direction.
