a home building contractor bought 4 2/8 acres for $165,000. What was the cost of each acre? (round to nearest dollar.)
pychu [463]

Answer: $38,824

Step-by-step explanation:

Convert the mixed number 4\ \frac{2}{8} as a decimal number.

Divide the numerator by the denominator and add it to the whole number 4. Then:

4+0.25=4.25acres

Then, knowing that 4.25 acres cost $165,000 , divide this amount by 4.25 acres to find the cost of each acre.

Therefore, you get that the cost of each acre rounded to nearest dollar is:

cost=\frac{\$165,000}{4.25}\\cost=\$38,824

Solve for 2.<br> -9x +5 &lt; 17 AND<br> 13x + 25 &lt; -1
Elena L [17]

Answer:

no solution

Step-by-step explanation:

-9x +5 < 17 AND   13x + 25 < -1

Solve each part separately and then put back together

-9x +5 < 17

Subtract 5 from each side

-9x+5-5< 17-5

-9x < 12

Divide each side by -9 remembering to flip the inequality

-9x/-9>12/-9

x > -4/3

and

13x + 25 < -1

subtract 25 from each side

13x +25-25 < -1-25

13x <-26

Divide by 13

13x/13 < -26/13

x <-2

There is no overlap so there is no solution
