Answer:
(5,7)
Step-by-step explanation:
(1,8)
(9,6)
x+x= 9+1=10
y+y= 8+6=14
ans. divide by 2
(5,7)
44
Step-by-step explanation:
let boys be x and girls be y
x/y=5/6
x=5y/6....(1)
if 6 boys join the club that will be x+6
Therefore:
(x+6)/y=13/12
13y=12x+72
13y-12x=72
Recall x=5y/6
Therefore:
13y-12(5y/6)=72
13y-(2*5y)=72
13y-10y=72
3y=72
y=24 people
Therefore:
x=(5*24)/6
x=20 people
Therefore people in the club before are 20+24=44
Answer:
6.06 x 
Step-by-step explanation:
(5.25 x 
) / (8.7 x 
)
= (5.25 x ) x( )/ (8.7 )
= (5.25 x 
)/ (8.7 )
= 0.606 x 
= 6.06 x
Answer:
75
Step-by-step explanation:
The sum of internal angles in a triangle is equal to 180
58 + 47 + x = 180
105 + x = 180 subtract 105 from both sides
x = 75
