Answer:
x=-3.5
Step-by-step explanation:
14/-4 = -3.5
1) 65% of x=5.2
65/100 of x=5.2
0.65x=5.2
x=5.2/0.65
x=8
2) 44% of x=55
44/100 of x=55
0.44x=55
x=55/0.44
x=125
3) 50% 0f x=7.5
50/100 of x =7.5
0.5x=7.5
x=7.5/0.5
x=15
4) 100% of x =21
100/100 of x=21
1x=21
x=21/1
x=21...........
Answer:
x = 23
Step-by-step explanation:
The exterior angle = sum of the 2 opposite interior angles, hence
2x + 3 + 51 = 100
2x + 54 = 100 ( subtract 54 from both sides )
2x = 46 ( divide both sides by 2 )
x = 23
