Answer:
no solution
Step-by-step explanation:
4y=-2(5-2y)
=4y = -10+4y
= 4y-4y=-10+4y-4y
=0-10
= undefined

Step-by-step explanation:
While solving an equation the first step is to get the variable (x) alone on either side.
2.3 x - 1.6 = 8.8 - 2.9 x
+ 1.6 +1.6
2.3 x = 10.4 - 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
-8.8 - 8.8
2.3 x - 10.4 = 2.9 x
2.3 x - 1.6 = 8.8 - 2.9 x
+2.9 x + 2.9 x
5.2 x -1.6 = 8.8
Answer:
8
Step-by-step explanation:
The sum of the internal angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5, hence
sum = 180° × 3 = 540°
Each exterior angle plus interior angle = 180°
Subtract each exterior angle from 180 for corresponding interior angle.
180 - 59 = 121, 180 - 77 = 103, 180 - 66 = 114, 180 - 62 = 118
Sum the 4 interior angles and subtract from 540 for 5 th interior angle
5 th = 540° - (121 + 103 + 114 + 118)° = 540° - 456° = 84°
The 5 th interior angle and 12x sum to 180 ( same reason as above )
Hence
12x + 84 = 180 ( subtract 84 from both sides )
12x = 96 ( divide both sides by 12 )
x = 8
