Answer:

~ -4x+4y+10

Explanation:

~ We have to collect like terms such as all the x’s, y and the normal numbers.

~ Then add like terms together: x-5x, 4y plus nothing, 3+7

~ After adding them, you should get -4x+4y+10.

Answer:

x = 2.5 + y

Step-by-step explanation:

Simplifying

x + 3 + -5x + 7 + 4y = 0

Reorder the terms:

3 + 7 + x + -5x + 4y = 0

Combine like terms: 3 + 7 = 10

10 + x + -5x + 4y = 0

Combine like terms: x + -5x = -4x

10 + -4x + 4y = 0

Solving

10 + -4x + 4y = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10' to each side of the equation.

10 + -4x + -10 + 4y = 0 + -10

Reorder the terms:

10 + -10 + -4x + 4y = 0 + -10

Combine like terms: 10 + -10 = 0

0 + -4x + 4y = 0 + -10

-4x + 4y = 0 + -10

Combine like terms: 0 + -10 = -10

-4x + 4y = -10

Add '-4y' to each side of the equation.

-4x + 4y + -4y = -10 + -4y

Combine like terms: 4y + -4y = 0

-4x + 0 = -10 + -4y

-4x = -10 + -4y

Divide each side by '-4'.

x = 2.5 + y

A general formula for the volume of a container is V = length x width x height (other words may be used in place of the three given).

3. 900 in^3, the fourth option

V = 20 x 15 x 3

V = 900 in^3

4. 288 in^3, the third option

V = 6 x 6 x 8

V = 288 in^3

Hope this helps!! :)

A. Ana bought a table having an area of

Anna35 [415]

Answer:

The side length of the table is x + 5

Step-by-step explanation:

To solve this, you need only take the square root of the area:

$\sqrt{x^2 + 10x + 25}\\= \sqrt{(x + 5)^2}\\= x + 5$

So the side length of the table is x + 5

The surface areas of two similar solids are 384 yd squared and 1057 yd squared The volume of the larger solid is 1795. What is t

Arturiano [62]

This is the concept of scale factors, we are required to calculate for the volume of the smaller solid if the larger solid has a volume of 1975.
Area scale factor=(linear scale factor)^2
thus;
Area scale factor=(area of larger solid)/(area of smaller solid)=1057/384
linear scale factor=√(1057/384)=5.7019
the volume scale factor=(linear scale factor)^3=[volume of larger solid]/[volume of smaller solid]
The volume scale factor=(5.7019)^3=185.3772
therefore;
volume of smaller solid=[volume of larger solid]/[volume scale factor]

=1795/185.3772
=9.683
The answer is 9.683 yd^3
