Answer:

Step-by-step explanation:
Given that when you add two numbers together the result is 3.
The greater of the number is given as a.
Let "x" represent that lesser number.
Thus:

To make x the subject of the formula. Subtract a from both x.


Therefore, the expression that represents the lesser number, x, is:

Answer:
If you have written the sides of both triangles in the same order , The congruent side will be ED . Else it could be anything . It would be more better if you could put a figure
I think it's Real numbers
8(x+18) is less than or equal to 19
Answer:
(−x, y)(x−4, y+2)
Step-by-step explanation:
If the figure is to be congruent, there must be no dilation. Any transformation having a multiplier on x or y cannot be a solution.
The only remaining choice is the one shown above, which involves a reflection across the y-axis and a translation.
