The answer is 50, just divide 10 and 2, you get 5 and multiply the 5 with the 10
8a+4s=840
a=s+30
8(s+30)+4s=840
12s+240=840
12s=600
s=50
A=s+30
a=50+30
a=80

Answer:
The slope of line for given points is 
Step-by-step explanation:
Given points of line as :
A = ( - 7 , 15 ) i, e
= - 7 ,
= 15
B = ( 10 , 27 ) i.e
= 10 ,
= 27
Let The slope of line be m
So , The slope with two points is given as equation
m = 
Or, m = 
Or, m = 
Hence The slope of line for given points is
