Answer:
You should buy from the first store
Step-by-step explanation:
Since there are 4 quarts in a gallon, we will need to multiply .80 by 8 to figure out how much it costs for 2 gallons. This will be $6.40 for the second store, and in order to find out how many the first store offers, we multiply 3 by two, which is six.
So, the first store charges $6.00 for two gallons, and the second store does $6.40 for two gallons of milk
Answer:
15 mph
Step-by-step explanation:
The cyclists will cover distance at a rate proportional to their speed. So, the distance ratio is ...
faster cyclist distance : slower cyclist distance = 3 : 1
Then the faster cyclist covers 3 : (3+1) = 3/4 of the total distance, or (3/4)(40 mi) = 30 mi.
That distance took 2 hours for the faster cyclist, so the speed was ...
speed = distance/time = 30 mi/(2 h) = 15 mi/h
Answer:
(5x − 6) (7x + 2)
Step-by-step explanation:
35x² − 32x − 12
Using AC method:
35 × -12 = -420
Factors of -420 that add up to -32: -42 and 10
Divide by 35 and reduce: -42/35 = -6/5, 10/35 = 2/7
Factors are (5x − 6) and (7x + 2).
35x² − 32x − 12 = (5x − 6) (7x + 2)
