Answer:
y = 26
Step-by-step explanation:
The angles of a linear pair total 180°.
__
(2y +1)° +(5y -3)° = 180° . . . . the sum of the angles is 180°
7y -2 = 180 . . . . . . divide by °, collect terms
7y = 182 . . . . . . . . add 2
y = 26 . . . . . . . . . divide by 7
_____
<em>Additional comment</em>
The angle measures are (2(26) +1)° = 53°, and (5(26) -3)° = 127°. These total 180°, as they should.
The answer to the question is all real numbers except 2 and 4.
To find the perimeter of a square, just add up all the lengths of the sides: The area of a square: To find the area of a square, multiply the lengths of two sides together... Another way to say this is to say "square the length of a side!" and for the rectangle, The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
It should be 10, when there is a double negative the signs become positive
