Jones has a 100-acre farm. he sells it to a developer who is going to build houses. the developer will use 10% of the land for s
Sholpan [36]
The first thing we must do is find the amount of land that will be used for the 120 lots.
 We must remember that 10% of the land will not be used for the lots.
 We have then:
 100 - (0.10) * (100) = 100 - 10 = 90 acres.&#10;
 Then, we must consider the following conversion of units:
 1 acre = 43560 ft ^ 2&#10;
 Applying the conversion we have:
 (90) * (43560) = 3920400 ft ^ 2&#10;
 Then, the amount of square feet for each lot is given by:
 3920400/120 = 32670 ft ^ 2&#10;
 Answer:
 
There will be 32670 square feet in each lot.

6j-k=23<br>3k+6j=11<br>Solve j and k ​using the elimination method on the simultaneous equations
frez [133]

Answer:

Step-by-step explanation:

6j - k = 23

6j + 3k = 11.....multiply by -1

---------------

6j - k = 23

-6j - 3k = -11 (result of multiplying by -1)

---------------

-4k = 12

k = -12/4

k = - 3 <=====

6j - k = 23

6j - (-3) = 23

6j + 3 = 23

6j = 23 - 3

6j = 20

j = 20/6

j = 10/3 <===

solution is : j = 10/3 and k = -3
