Vertex segment That will probaly be a answer
Answer:
The value of y s 2.5
Step-by-step explanation:
Vertical angles are always equal to one another. In this case, we can find the angles by setting the two values equal and solving algebraically.
2y + 5 = 4y
5 = 2y
2.5 = y
<em>Note: I am assuming your second equation is:</em>
<em>x = 2y - 1</em>
<em></em>
Answer:
The solution to the system of equations is:
Step-by-step explanation:
Given the system of equations
2x+y=3
x = 2y - 1
solving the system of equations using the elimination method
Arrange equation variables for elimination
Multiply x-2y=-1 by2: 2x-4y=-2
subtracting the equations
now solve -5y = -5 for y
Divide both sides by -5
Simplify
For 2x+y=3 plug in y=1
subtract 1 from both sides
Simplify
Divide both sides by 2
Simplify
Therefore, the solution to the system of equations is:
the answer should be 49mm
28*7 / 4 = 49
