Subtract 7.8 points by 4.8 and you get 3.4 !!
Complete question :
Harry fills up his Jeep with gasoline and notes that the odometer reading is 23,568.7 miles. The next time he fills up his Jeep, he pays for 12.6 gallons of gasoline. He notes his odometer reading is 23,706.3 miles. How many miles per gallon did he get?
Answer:
10.9 miles per gallon
Step-by-step explanation:
Given that :
Odometer reading when filled up with gasoline = 23,568.7 miles
Odometer reading with 12.6 gallons of gasoline = 23,706.3 miles
Miles per gallon gotten :
(Current Odometer reading - reading when filled up) / gallon of gasoline
(23706.3 - 23568.7) / 12.6
= 10.920634
= 10.9 miles per gallon
Answer:
- team: 8 kph
- current: 4 kph
Step-by-step explanation:
The downstream speed is ...
speed = distance / time
speed = 36 km/(3 h) = 12 km/h
The upstream speed is ...
12 km/(3 h) = 4 km/h
__
If b and c represent the speeds of the boat and current, respectively, then we have ...
b + c = 12
b - c = 4
Adding these gives ...
2b = 16
b = 8
c = b -4 = 4
The rate of the rowing team in calm water is 8 km/h; the rate of the current is 4 km/h.
Answer:
y = x + 8
Step-by-step explanation:
- Find the slope: ( parellel lines have the same slope)
- Create an equation using the given ordered pair to find the
y-intersept (b): 10 = (6) + b
- Reduce the numbers with the greatest common factor 3 : 10 = 2 + b
- Move the variable to the left-hand side and change its sign : -b + 10 = 2
- Calculate the diffrence : -x = -8
- Change the signs on both sides of the equation: x = 8
Use the slope and y-itersept to creat the equation : y = x + 8
