Step-by-step explanation:
5x - 2y = 10
-5x -5x
----------------------
-2y = 10 - 5x
/-2 /-2
--------------------
y = -5 + 2.5x
Algebra is a very important branch of math.
Algebra is a lot like arithmetic which means it follows all the rules of arithmetic, and it still uses the four main operations that arithmetic is built on.
In arithmetic, the only thing that was unknown was the answer to the problem. For example, 39 + 2 = 41. In algebra, we use a variable to represent the number. A variable is a letter that represents any number. The most common variable is "x".
Answer:b and c
Step-by-step explanation:

Two pairs of corresponding angles are congruent, so the triangles are similar.
The correct option is (A).
<h3> What is similarity in triangles?</h3>
Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
As, the measurement of two angles are equal.
So, the angles are congruent.
Hence, by AA criteria the triangles are similar.
