Answer:
7 sweets for Henry
Step-by-step explanation:
Let their respective shares be 4x,x,and 3x for Richard,Henry and Gavin
If Richard gets 7 more sweets than Gavin then the difference between their shares is 7 that is
4x-3x=7
x=7
To find Henry's share,
AC+CB+BA=180
2x+23+3x-8+4x+1=180
9x+16=180
9x=180-16
9x=164
x=164/9
x=18.2
question
D
Since they are the same variables
their are 17 cows
7x2=14
82-14=68
68/4=17
