Answer:
-15
Step-by-step explanation:
as i said if the signs are different the result is negative
23-9= 14
14 divide by 2 = 7
so 7 baseball cards in a packet
Answer:
1 basket = 24 apples
24 × 18 = 432 apples
(use cross multiplication method)
1 apple = 15 cents
432 = x
![\frac{1x}{1} = 6.480](https://tex.z-dn.net/?f=%20%5Cfrac%7B1x%7D%7B1%7D%20%20%3D%206.480)

Answer: ![Ely, Chris, Jim, Dory](https://tex.z-dn.net/?f=Ely%2C%20Chris%2C%20Jim%2C%20Dory)
Step-by-step explanation:
The distances must be expressed in the same uni.
Let's express the distance in meters.
We know that Dory lives 2.5 miles from school.
Since:
![1\ mi = 1.61\ km](https://tex.z-dn.net/?f=1%5C%20mi%20%3D%201.61%5C%20km)
The distance in kilometers is:
![(2.5\ mi)(\frac{1.61\ km}{1\ mi})=4.025\ km](https://tex.z-dn.net/?f=%282.5%5C%20mi%29%28%5Cfrac%7B1.61%5C%20km%7D%7B1%5C%20mi%7D%29%3D4.025%5C%20km)
Since ![1\ km = 1,000\ m](https://tex.z-dn.net/?f=1%5C%20km%20%3D%201%2C000%5C%20m)
The distance in meters is:
![(4.025\ km)(\frac{1,000\ m}{1\ km})=4,025\ m](https://tex.z-dn.net/?f=%284.025%5C%20km%29%28%5Cfrac%7B1%2C000%5C%20m%7D%7B1%5C%20km%7D%29%3D4%2C025%5C%20m)
Jim lives 3.2 kilometers from school. The distance in meters is:
![(3.2\ km)(\frac{1,000\ m}{1\ km})=3,200\ m](https://tex.z-dn.net/?f=%283.2%5C%20km%29%28%5Cfrac%7B1%2C000%5C%20m%7D%7B1%5C%20km%7D%29%3D3%2C200%5C%20m)
Chris lives 3,000 yards from school.
Since:
![1\ m = 1.09\ yd](https://tex.z-dn.net/?f=1%5C%20m%20%3D%201.09%5C%20yd)
The distance in meters is:
![(3,000\ yd)(\frac{1\ m}{1.09\ yd})=2,752.29\ m](https://tex.z-dn.net/?f=%283%2C000%5C%20yd%29%28%5Cfrac%7B1%5C%20m%7D%7B1.09%5C%20yd%7D%29%3D2%2C752.29%5C%20m)
Therefore, the order of the students from closest to farthest from school is:
![Ely, Chris, Jim, Dory](https://tex.z-dn.net/?f=Ely%2C%20Chris%2C%20Jim%2C%20Dory)
