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...........
First, add or subtract all variables
y2 + 4y - 16y + 3y = -7y
-7y + 2 is your answer
Your answer is 60 because you multiply 600 with .10 and get 60.00
I dont believe there is any figure we can see, take a larger picture please
