You could add the two x-coordinates together (in this case, 0 and 20) and then divide them by 2 to get an x-coordinate of 10 for their midpoint.
I believe the answer to your question is A
Answer:
5
Step-by-step explanation:
We have x-2 = 5
x-2 = 5 we separate parenthesis.
x(-2) = 5(+2)
x = 7
We can check this as what the x-2 is saying is 7-2 = 5
The fastest racehorses can run a mile in a little over a minute and a half.
Use a proportion.
Let the unknown height of the building be x.
x is to 39 m as 59 cm is to 71 cm.
x/39 = 59/71
71x = 39 * 59
x = 2301
x = 32.4
Answer: A. 32.4 m
