Answer:
The area is 78.5, the farmer does have enough space to plant his vegetables 
Step-by-step explanation:
To find the area, you need to use the formula, A=πr², (make sure the diameter is turned into the radius by dividing by 2, in this case, it's 5 as the radius)
Plug in your numbers, A= 3.14(5)²
                                     A= 3.14(25)
The area is 78.5
So the farmer does have enough space to plant his vegetables since 78.5 is greater than 25
 
        
             
        
        
        
Answer:
x = 136/35; y = -⁹/₁₀
Step-by-step explanation:
(1)         7x + 8y = 20
(2)        7x – 2y = 29       Subtract (2) from (1)
                   10y =  -9        Divide each side by 10
(3)                  y =  -⁹/₁₀     Substitute (3) into (1)
       7x - 2(-⁹/₁₀) = 29
       7x + 18/10  = 29                       Subtract 18/10 from each side
       7x              =      29 - 18/10
       7x              = (290 - 18)/10
       7x              =          272/10        Divide each side by 7
         x              =           272/70
         x              =           136/35
x = 136/35; y = -⁹/₁₀
Check:
(1) 7(136/35) + 8(-⁹/₁₀) = 20
       136/5    -   72/10 = 20
       136/5    -   36/5  = 20
                       100/5  = 20
                        20      = 20
(2) 7(136/35) – 2(-⁹/₁₀)  = 29
        136/5    +    18/10 = 29
        136/5    +      ⁹/₅    = 29
                         145/5  = 29
                         29       = 29
