The answer is 15 km I think.
Answer:
13,I
Step-by-step explanation:
set the 3 number is 3/5, x,y
product of them
3 /5 xy = 7:6
xy = 7:6 x 5 /3
Xy = 13
So the two number is 13, 1
Answer:
C. 3
Step-by-step explanation:
Formula for slope is given as ![m = {y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=%20m%20%3D%20%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20)
The coordinates of any two points can be used in this formula. Let's use, (1, 5) and (2, 8).
Let,
![(1, 5) = (x_1, y_1)](https://tex.z-dn.net/?f=%20%281%2C%205%29%20%3D%20%28x_1%2C%20y_1%29%20)
![(2, 8) = (x_2, y_2)](https://tex.z-dn.net/?f=%20%282%2C%208%29%20%3D%20%28x_2%2C%20y_2%29%20)
Plug the values into the formula:
![m = {8 - 5}{2 - 1}](https://tex.z-dn.net/?f=%20m%20%3D%20%7B8%20-%205%7D%7B2%20-%201%7D%20)
![m = {3}{1}](https://tex.z-dn.net/?f=%20m%20%3D%20%7B3%7D%7B1%7D%20)
![m = 3](https://tex.z-dn.net/?f=%20m%20%3D%203%20)
For the first digit, you have two possible choices: 1 or 2. For *each* of those choices, you can choose 1 or 2 for the second digit in the number, and for each of *those*, you can choose 1 or 2 for the third digit of the number.
That’s 2 * 2 * 2 or 8 possible 3-digit numbers you can make with the digits 1 and 2.
Answer:
3+(-4)= -1
Step-by-step explanation:
Originally on 3 and goes to -4, and for addition add (-4) to positive 3 and you'll get -1
