Answer:
17
125
Step-by-step explanation:
exterior angle is equal to sum of interior opposite angle. so 
( 2x + 6 ) + ( 5x ) = ( 8x - 11 )
 7x + 6 = 8x - 11
 x = 17 
exterior angle = ( 8 * 17 ) - 11 = 125

Answer: 5
Step-by-step explanation:
weekday hours x*2
weekend hours y*10
x+y=26
2x+10y=220
----------------------
x=26-y
2(26-y)+10y=220
52-2y+10y=220
8y=220-52
8y=168
y=168/8
y=21 
x=26-21=5
x=5
 
        
             
        
        
        
Answer:
Part A = D
Part B = 5 and 50 
Step-by-step explanation:
Part A:
area = 5*4x = 20x
so, 
Part B:
to leave it only by x, you divide both sides by 20 
100/20 = 5, 1000/20 = 50
which 
 
        
             
        
        
        
Answer:
Step-by-step explanation:
in y = mx + b form, the slope is in the m position and the y intercept is in the b position.
y = mx + b
slope(m) = 5/7
y int (b) = -3
y = 5/7x - 3 <===
