A 40% antifreeze solution is to be mixed with a 70% antifreeze
Alenkasestr [34]

Answer: 160 liters of the

40% solution and 80 liters of the 70% solution will be used.

Step-by-step explanation:

Let x represent the number of liters of 40% antifreeze solution that should be used.

Let y represent the number of liters of 70% antifreeze solution that should be used.

The volume of the mixture to be mixed is 240 liters. It means that

x + y = 240

The 40% antifreeze solution is to be mixed with a 70% antifreeze

solution to get 240 liters of a 50% solution. This means that

0.4x + 0.7y = 0.5(240)

0.4x + 0.7y = 120 - - - - - - - - - - - -1

Substituting x = 240 - y into equation 1, it becomes

0.4(240 - y) + 0.7y = 120

96 - 0.4y + 0.7y = 120

- 0.4y + 0.7y = 120 - 96

0.3y = 24

y = 24/0.3

y = 80

x = 240 - y = 240 - 80

x = 160

Elkton Heights 16 miles each day on a 12 day hiking trip Lola height 14 miles each day on her 16 day hiking trip and all how man
babunello [35]

Answer:

32

Step-by-step explanation:

To compare how much more Lola hiked we need the miles that each one hiked.

Elton hiked 16 miles each day for 12 days, the total amount of miles he hiked we can found by multiplying 16 by 12:

16miles(12) = 192 miles

Lola hiked 14 miles each day but for 16 days, so the total amount of miles she hiked can be found by multiplying 14 by 16:

14miles(16days) = 224

The difference of miles we found by subtracting 192 (elton's miles) from 224 (lola's miles)

224 - 192 = 32
