I have no idea. Please I need just answers. Thank you. ​
igomit [66]

Answer:

Step-by-step explanation:

1km = 1000m

5a. 5.768km = 5768m = 57.7m

5b. 9.039km = 9039m = 90.4m

5c. 8.48km = 8480m = 84.8m

5d. 17.685km = 17685m = 17.7m

5e. 17.658km = 17658m = 17.7m

To round to the nearest 100m just divide by 100 and then round it off. like 57.68=57.7m because 8 is more than 5 so 6 becomes 7 to one decimal.

Rule is applied for all the other questions too.

Find the ordered pairs for x and y intercepts of the equation 3x - 2y =18
My name is Ann [436]
                  
                                                           3x - 2y = 18
Wherever the line crosses the
x-axis, y=0.                                         3x        = 18
                                                             x        =  6
The x-intercept is                                    (6, 0)  .


                                                           3x - 2y = 18
Wherever the line crosses the
y-axis,  x=0.                                            - 2y = 18
                                                                   y = -9
The y-intercept is                                        (0, -9)  .
