Answer: Corn = 200 acres
Wheat= 400 acres
Step-by-step explanation:
Let the number of acres of corn = c
Let the number of acres of wheat = w
The Mulder Farm has 600 acres of land allotted for raising corn and wheat. This will be:
c + w = 600
c = 600 - w
Cultivation cost equals:
= 40c + 25w = 18000
Since c = 600 - w, we slot it into the equation
40c + 25w = 18000
40(600 - w) + 25w = 18000
24000 - 40w + 25w = 18000
Collect like terms
24000 - 18000 = 40w - 25w
6000 = 15w
w = 6000/15
w= 400
400 acres of wheat will be planted
Since c + w = 600
c = 600 - 400
c = 200
200 acres of corn should be planted

Answer:
x = 2
Step-by-step explanation:
7x−5=2x+5
step 1 add 5 to each side
-5 + 5 = cancels out
5 + 5 = 10
we now have 7x = 2x + 10
step 2 subtract 2x from each side
2x - 2x cancels out
7x - 2x = 5x
we now have 10 = 5x
step 3 divide each side by 5
5x / 5 = x
10 / 5 = 2
we' re left with x = 2
