Answer: the cost of one apple is $1
Step-by-step explanation:
Let x represent the cost of one apple.
Let y represent the cost of one Pomegranate.
Donata bought 3 Apples and 5 Pomegranates at the local supermarket for a total of $16.50. This means that
3x + 5y = 16.5 - - - - - - - - - - - - -1
Meaghan bought 6 Apples and 11 Pomegranates at the same store for a total of $35.70. This means that
6x + 11y = 35.7- - - - - - - - - - - - -2
Multiplying equation 1 by 2 and equation 2 by 1, it becomes
6x + 10y = 33
6x + 11y = 35.7
Subtracting, it becomes
- y = - 2.7
y = 2.7
Substituting y = 2.7 into equation 1, it becomes
3x + 5 × 2.7 = 16.5
3x + 13.5 = 16.5
3x = 16.5 - 13.5 = 3
x = 3/3 = 1
Answer: The person's speed is 8 miles per hour.
Step-by-step explanation:
To solve we want to convert the 
and 
proportionally for the number of miles per hour. We know that multiplying a fraction by its reciprocal will equal 1. So let's do that for the value of the hour.
×
Since we multiplied that to the number of hours we must also do that for the number of miles.

You would need 6 quarts of milk. You would do 24(2) then you take 48 and divide it by 288 and you get 6.
Answer:
- The submarine's position means the distance it traveled is greater than 24 feet
- A possible position of the submarine is -27 feet
Step-by-step explanation:
Distance is generally a positive number. (Displacement, or position may be negative, as in this case.) If the sub started at 0 feet and went lower than -24 feet, it traveled a distance of more than 24 feet (greater than 24 ft).
Of the numbers listed, the only one lower than -24 is -27.
1 equals 0.46 (make a line over the 6 to show it is repeated)
2 equals 0.4 (make a line over the 4 to show it is repeated)
3 equals -0.6 (make a line over the 6 to show it is repeated)
4 equals -0.857142 (make a line over all numbers past the decimal to show it is repeated)
5 equals 3.3409 (make a line over the 09 at the end to show it is repeated)
6 equals -1.7727 (make a line over the 27 at the end to show it is repeated)
7 equals 66.5%
8 equals 3.16 (make a line over the 6 to show it is repeated)
9 equals -9 over 10
10 equals -17 over 20
11 equals -3 and 4 over 5
