Answer:
25 Months
Step-by-step explanation:
Let's make the equations first,
Plan A: 70x Plan B: 50x+500...
Now we make it into an equivalent equation:
70x=50x+500...
Then we solve:
70x=50x+500-50x -50x20x=500...
÷20 ÷20x=25...
To check if it's correct, we just plug it in:
70(25)=50(25)+500...
1750=1750...

Answer:
The farmer would need 80 posts.
Step-by-step explanation:
If one side of the garden is 10m long, and the garden is a square, we can assume that all 4 sides will be 10m. That makes it 40m in total. Times 40×2 and you get 80.

Given,
y = -3x+1 (EQ1)
y = 2x-4 (EQ2)
Equate EQ1 and EQ2
EQ1 = EQ2
-3x+1 = 2x-4
-3x-2x = -4-1
x = 1
y = -3x+1
y = -3(1)+1
y = -3+1
y = -2
(1, -2)
