B. 5x−15y=1
C. 15x+5y=−1
D. 15x−5y=−1
Answer:
Option A is correct.
Step-by-step explanation:
The standard of any equation is in the form of:
Given the equation:
Multiply both sides by 5 we get;
Subtract 5y from both sides we get;
or
Therefore, the equation in standard form is
Answer: 15x−5y=1
Step-by-step explanation:
Depending on what is known about triangles ABC and EDC, either the Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), or Hypotenuse-Leg (HL) Postulate might be used to prove their congruence.
In mathematics, there are several postulates that can be used to prove that two triangles are congruent (i.e., identical in shape and size). In the case of triangles ABC and EDC, the appropriate postulate would depend on what information we have about these triangles. If we know that corresponding sides and angles are equal, we could apply the Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), or Hypotenuse-Leg (HL) Postulate. Without specific details about triangles ABC and EDC, I can't determine which postulate would prove their congruence.

y-5x+12
5x+y=12
y-12=5(4-0)
5x+y=-1
Answer:
y=7 so all of the y's are 7 but the last one is 4
