omeli [17]

Answer:

The height is 10in

Step-by-step explanation:

If you need to calculate the volume, you need to know the formula. The formula is length x width x height. You have the length and width, so you need the height. 2.5in x 15in x 10in = 375 in^3. You may ask why it is inches cubed instead of inches. It is inches cubed because you multiplied three inches together.

In order to solve the following system of equations by addition, which of the

Pavlova-9 [17]

Answer:

Multiply the top equation by -3 and the bottom equation by 2

Step-by-step explanation:

Given system of equations:

$\begin{cases}4x-2y=7\\3x-3y=15 \end{cases}$

To solve the given system of equations by addition, make one of the variables in both equations sum to zero. To do this, the chosen variable must have the same coefficient, but it should be negative in one equation and positive in the other, so that when the two equations are added together, the variable is eliminated.

To eliminate the variable y:

Multiply the top equation by -3 to make the coefficient of the y variable 6:

$\implies -3(4x-2y=7) \implies -12x+6y=-21$
