If the perimeter is 26 and the length of one side of the rectangle is 5cm longer than its breadth,
26 - 5 - 5 = 16
16 / 4 = 4 ( rectangle has 4 sides. )
the breadth is 4cm.
so the length must be 4+5=9cm.
1) 180° - 146° = 34
9х - 2 = 34
9х = 34 + 2
9х = 36
х = 36 : 9
х = 4
-------------
2) (9х - 2) + (6у + 44) = 180°
(9 * 4 - 2) + (6у + 44) = 180
(36 - 2) + (6у + 44) = 180
34 + 6у + 44 = 180
6у = 180 - 34 - 44
6у = 102
у = 102 : 6
у = 17
---------------
There are so solutions because they don’t intersect
The answer is 1th and 2 nd
Answer:
Sara could list the factors of 18 and 30 then find the greatest value the lists have in common. The length of the longest equal-sized pieces she can cut from both boards, with no wood left over, is 4.8 inches. She will be able to cut 3.75 pieces from the 18-inch board and 2.08 pieces from the 30 inch board. She would have enough wood to cut 10-equal pieces for he club project.
