How do you use the additive inverse to evaluate an expression that uses subtraction?

Harlamova29_29 [7]

You use additive inverse to combine like terms that are on opposite sides of the equation.
ie.
3x + 1 = 6x -12
You use additive inverse to move -12 to the +1

Katen [24]

Answer:

The area of the wall that she will paint in two rolls is <u>219.8 inches²</u>.

Step-by-step explanation:

Given:

Jenny uses a roller to paint a wall. The roller has a radius of 1.75 inches and a height of 10 inches.

Now, to find the area of the wall that she will paint in two rolls.

So, we find the lateral surface area of roller.

Radius (r) = 1.75 inches.

Height (h) = 10 inches.

So, to get the lateral surface area we put formula:

$A_{L} =2\pi rh$

$A_L=2\times 3.14\times 1.75\times 10$

$A_L=109.9\ inches^2.$

Thus, the lateral surface area of the roller = 109.9 inches².

Now, to get the area of wall that she will paint in two rolls we multiply 2 by the lateral surface area of the roller:

$109.9\times 2\\\\=219.8\ inches^2.$

Therefore, the area of the wall that she will paint in two rolls is 219.8 inches².

What is the qoutient of 1/6 and 2/9

beks73 [17]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

To find the quotient, we first need to know what quotient means.

Quotient is the solution to division problems.

So here is how we have to do this, first we identify our fractions:

$\frac{1}{6} and \frac{2}{9}$

Next, we must turn the fraction we are dividing by into a reciprocate:

$\frac{2}{9} turns into \frac{9}{2}$

Now we have $\frac{1}{6} and \frac{9}{2}$

Next, we multiply!:

$\frac{1}{6} x \frac{9}{2} = \frac{9}{12}$

Simplified:

$\frac{3}{4}$

The rectangular prism shown has a surface area of 488 square inches. What is the length of the prism?

BigorU [14]

Answer:

length of the prism = 244 - (width x height) / width + height)

Step-by-step explanation:

Let length be a and width be b and height be c

2 (a * b) + 2 (b* c) + 2 (a * c) = 488

2ab+ 2bc + 2ac = 488

ab + bc + ac = 244

ab + ac = 244 - ac

a (b + c) = 244-ac

a = 244-bc / b + c

Therefore the length of the prism = 244 - (width x height) / width + height)
