Im pretty sure you don't need help with this.this is from a week ago
        
             
        
        
        
Y+4<u><</u>9
subtract 4
y<u><</u>5
y is smaller than and equal to 5
so you shade from 5 to the negative end to infinity (to the left) and shade the 5 to show that it is included (attachment says A)
6 less than (-6) 2 times a number (2 time x) is greater than (>) 8 (8)
-6+2x>8
add 6
2x>14
divide 2
x>7
so 
x is bigger than 7
shade from 7 to the positive end to infinity (to the right) and don't shade 7 but put a circle around it to show that it is not included (attachment says B )
I have included pictures of the number lines
 
        
        
        
Answer:
The dimensions of the garden is 102 feet by 68 feet 
Step-by-step explanation:
Here, we want to get the width and length of the garden 
The perimeter is represented by the length of the fencing 
From the question;
w = 2l/3 
The formula for the perimeter is;
P = 2(l + w)
Thus;
340 = 2(l + 2l/3)
170 = (l + 2l/3)
Multiply through by 3 
510 = 3l + 2l
5l = 510 
l = 102 feet 
w = 2/3 * l
w = 2/3 * 102
w = 68 feet
