-5x + 9y = 14 -3x + 9y = -6

1 answer:

4 0

You can solve it by several ways, but easiest and shortest would be "By Elimination"

So, subtract 2nd equation from 1st,
-2x = 20
x = -10

Substitute it in 2nd equation,
-3(-10) + 9y = -6
30 + 9y = -6
9y = -6 - 30
y = -36/9
y = -4

In short, Your Answer would be: (-10, -4)

Hope this helps!

Answer:

The length, the width and the height of the box is 6 inches.

Step-by-step explanation:

Given:

Daisy making a memory box in the shape of the cube.

The total volume is 216 cubic inches.

Now, to find the length, width and height of the cube.

Volume of cube = 216 cubic inches.

As, the sides of the cube are having same length.

Thus, the measurements of length, width and height of the cube are same.

Now, to get the side of the cube we put formula:

$Volume=(side)^3\\\\216=(side)^3$

Using cube root on both sides:

$6=side\\\\Side=6\ inches.$

Therefore, the length, the width and the height of the box is 6 inches.
