Answer:
Albuquerque is 345 miles away from Flagstaff.
Step-by-step explanation:
We are given three cities:
The journey took place as:
L.A.--to-----Flagstaff-----to-----Albuquerque.
The distance between L.A. to Albuquerque is 810 miles.
Let the distance between Flagstaff to Albuquerque be 'x' miles.
Also we are given that the distance from L.A. to Flagstaff is 120 miles greater than the distance from Flagstaff to Albuquerque.
i.e. distance from L.A. to Flagstaff is 120+x.
therefore, 120+x+x=810
⇒ 120+2 x=810
⇒ 2 x=690
⇒ x=345.
Hence, the distance between Flagstaff and Albuquerque is 345 miles.
How much does a bottle of water cost?
How much does a gallon of milk cost?
Answer:
Cost of a snack size bag of chips = $0.8
Cost of a water bottle = $1.6
Cost of a gallon of milk = $3.4
Step-by-step explanation:
Let the cost of water bottle = $a
Cost of 1 gallon milk = $b
and cost of 1 bag of chips = $c
So, cost of 4 gallons of milk, 6 bottles of water and 5 bags of chips = $(4b + 6a + 5c)
4b + 6a + 5c = 27.2 -----(1)
Cost of one water bottle = 2 × cost of one bag of chips
a = 2c -----(2)
A gallon of milk = cost of water bottle + $1.80
b = a + 1.8
From equation (2)
b = 2c + 1.8 -----(3)
Now we substitute these values from equations (2) and (3) in equation (1)
4(2c + 1.8) + 6(2c) + 5c = 27.2
8c + 7.2 + 12c + 5c = 27.2
25c = 27.2 - 7.2
c =
c = $0.8
From equation (2)
a = 2×0.8
a = $1.6
From equation (3)
b = 2(0.8) + 1.8
b = 1.6 + 1.8
b = $3.4
Therefore, cost of a snack size bag of chips = $0.8
Cost of a water bottle = $1.6
Cost of a gallon of milk = $3.4
