There is a mound of g pounds of gravel in a quarry. throughout the day, 400 pounds of gravel are added to the mound. two orders of 900 pounds are sold and the gravel is removed from the mound. at the end of the day, the mound has 1,500 pounds of gravel. write the equation that best describes the situation.

The equation that best describes the given situation is  and this can be determined by forming the linear equation with the help of given data.

Given :

Let the initial amount of gravel be 'g'. Then after the addition of 400 pounds of gravel, the total gravel becomes:

= g + 400

Given that two orders of 900 pounds are sold and the gravel is removed from the mound so, the total gravel now becomes:

= g + 400 - 1800

= g - 1400

At the end of the day, the mound has 1,500 pounds of gravel, that is:

g - 1400 = 1500

g = 1500 + 1400

g = 2900

Therefore, the equation that best describe the given situation is:

g + 400 - 1800 = 1500

The equation that best describes the situation is:

Step-by-step explanation:

The initial amount of gravel is g.

Then we know that 400 pounds are added

Two orders of 900 pounds are sold and the gravel is removed from the mound. This is:

At the end of the day, the mound has 1,500 pounds of serious. This is:

The equation that best describes the situation is:

And

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
