Answer:

Only a factor of 6 was removed from the second term. A factor of 6x should have been removed.
6x(5 -2y)

Step-by-step explanation:

The distributive property lets you apply a multiplier to a group of terms. The entire multiplier is applied to each and every term. When making use of this property to rewrite expressions, one must make sure the rewritten expression is completely equivalent to the original.

... 30x -12xy = 6x·5 -6x·2y = 6x(5 -2y)

_____

6x(5 -2xy) = 30x -12x^2y ≠ 30x -12xy

The second term in parentheses has a factor of x that shouldn't be there.

Darcy harvest 8 3/4 acres of corn every 5/6 of an hour. How many acres per hour?

otez555 [7]

Answer:

The answer is $10\frac{1}{2}\ per\ hour.$

Step-by-step explanation:

Given:

Darcy harvest 8 3/4 acres of corn every 5/6 of an hour.

Now, to find the acres per hour it takes to harvest.

Darcy harvest = $8\frac{3}{4}=\frac{35}{4}\ acres.$

The time he took to harvest = $\frac{5}{6}\ hour.$

So, to get the acres per hour we put formula:

$Distance = \frac{35}{4}\ acres.$

$Time=\frac{5}{6}\ hour.$

$Speed=\frac{distance}{time}$

$Speed=\frac{\frac{35}{4}}{\frac{5}{6}}$

$Speed=\frac{35}{4}\times \frac{6}{5}$

$Speed=\frac{210}{20}$

$Speed=\frac{21}{2}$

$Speed=10\frac{1}{2}\ per\ hour.$

Therefore, the answer is $10\frac{1}{2}\ per\ hour.$
