Answer:

Step-by-step explanation:

First, we should line up the fractions.

6 / 7 - 6 / 7.

Second, we subtract straight across since denomionators are the same.

6 / 7 - 6 / 7 = 0.

Therefore, the difference is 0.

Answer: 0

Step-by-step explanation: To subtract like fractions such as 6/7 - 6/7, we simply subtract the numerators and keep the original denominator.

So in this problem, we subtract 6 - 6 to get 0 and we keep the denominator of 7 which gives us 0/7.

When we have 0 in the numerator of a fraction, it simplifies to just 0.

This means that 6/7 - 6/7 = 0.

X² - 7x +12 = 0
(x-3)(x-4)=0
x= 3 or 4
since the leading coefficient is positive the parabola opens up and the vertex is a minimum

Marlo uses 252 lb of gravel to cover a garden plot of 36 ft2. How many pounds of gravel does it take to cover one square foot? H

irakobra [83]

The area and the amount of gravel are illustrations of proportions.

7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

The given parameters are:

$252\ lb= 36ft^2$

The number of pound for an area of <em>1 square foot </em>is calculated as follows:

$x = 1ft^2$

So, we have:

$x = 1ft^2$

$252\ lb= 36ft^2$

Cross multiply

$x \times 36 = 252 \times 1$

Divide both sides by 36

$x = 7lb$

The area to be covered with 315lb gravel is calculated as follows:

$315lb = y$

So, we have:

$315lb = y$

$252\ lb= 36ft^2$

Cross multiply

$y \times 252 = 36 \times 315$

$y \times 252 = 11340$

Divide both sides by 252

$y = 45$

Hence, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
