Put 3x in for y, so the equation will be 3x=2x-7. Then solve. once you find “x”, plug it back into one of the original equations. And then you have x and y

The following is an incomplete paragraph proving that the opposite sides of parallelogram ABCD are congruent:
Semmy [17]

Answer:  Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem.

Step-by-step explanation:

Given : ABCD is a parallelogram.

That is, AB ║ CD and AD ║BC

We have to prove that: AB≅CD and AD≅BC

Proof:

Construct diagonal AC in the parallelogram ABCD.

Since, AC ≅ AC ( reflexive)

∠ BAC ≅ ∠ DCA  ( By the alternative interior angle theorem)

∠ BCA ≅ ∠ DAC   ( By the alternative interior angle theorem)

⇒ Δ BCA ≅ Δ DAC ( By ASA congruence postulate )

⇒ AB≅CD as well as AD≅BC ( BY CPCTC )

Thus, the opposite side of the parallelogram are congruent.

A stone is an English measure of weight. There are 14 lb in 1 stone and 2.2 lb in 1 kg. A certain person weighs 9 stone.
USPshnik [31]
For every one stone it's 14lb and for every kg it's 2.2 lb therefore you would have to multiply 14 by 9 then divide that answer by 2.2 and that answer will be your answer..
14•9=126
126÷2.2=57.27
You would have 57.27kg or if rounded you would have 57kg
Hope this helps
