Answer:
(-3,-10)
Step-by-step explanation:
Given part a, you seem to know the midpoint formula. We can easily edit that to figure out what an endpoint is. Say that a variable "a" represents the x coordinate of D, and b the y coordinate. As the x coordinate of M is 0.5, and the x coordinate of C is 2, we can use the midpoint formula to say that 
. Multiplying both side by 2, we get that a+2=-1, and subtracting both sides by 2, a=-3. Similarly, 
, b+7=-3, and b=-10, making our answer (-3, -10). Let me know if you have any questions.
Answer:
A. How much Anna weights in kilograms is what is asked (Btw is it her or his?)
B. The values given is 54000 (most likely in grams )
C. The operation that is going to be used is 1000 since kilograms is 1000 grams
D. The solution is 54 kilograms
E. To get 54 kilograms to grams we can just multiply by 1000 again which will result into 54000 thus the answer is correct
Step-by-step explanation:
A:
The question is asked when there is a "what" or a problem statement
B:
The only value or digits given is 54000
C:
in the Metric Scale Kilograms is 1000 times larger in value than grams thus 1000
D:
Divide 54000 with 1000 which is 54
E:
Um.... just multiply 1000 ._. (That's the only way I can check it)
Hope this helps!
