A farmer wants to buy between 90 and 100 acres of land. • He is interested in a rectangular piece of land that is 1,500 yards long
and 300 yards wide.
The piece of land is being sold as one complete unit for $87,000.
If the farmer does not want to spend more than $900 an acre, does the
land meet all of his requirements? (1 acre = 43,560 ft)
A. Yes, the amount of land satisfies his needs, and the price is low enough.
B. No, the price is low enough, but there is too much land.
C. No, the price is low enough, but there is not enough land.
D. No, the amount of land satisfies what he needs, but the price is too
high.

your answer would be 10x - 1

answer: 5

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
