Answer:
Given a square ABCD and an equilateral triangle DPC and given a chart with which Jim is using to prove that triangle APD is congruent to triangle BPC.
From the chart, it can be seen that Jim proved that two corresponding sides of both triangles are congruent and that the angle between those two sides for both triangles are also congruent.
Therefore, the justification to complete Jim's proof is "SAS postulate"
Step-by-step explanation:
How did who figure out what answer?
Answer:
3 centimeters
Step-by-step explanation:
given ratio is
18 km : 1 cm
Now if km is multiplied by 3, the cm should also be multiplied by 3.
=> 18 x 3 : 1 x 3
=> 54 km : 3 cm
I have solved some examples in the picture
If anything is unclear let me know.

Use substitution
Set them equal to each other
-3x + 4 = 3x - 2
Solve the equation
4 = 6x - 2
6x = 6, x = 1
Plug in 1 for any equation to find y
Y = -3(1) + 4
Y = -3 + 4, y = 1
Solution: x = 1, y = 1
