Vinil7 [7]

Answer:

0.16 gallons of paint are used on each piece of furniture.

The answer lies between the whole numbers 0 and 1.

Step-by-step explanation:

we know that

Four gallons of paint are used to paint 20 chairs and 5 small tables.

if each chair and table used the same amount of paint

then

sum the total pieces of furniture

20+5=25 pieces

Find the unit rate

Divide the total gallons of paint used by the total pieces

\frac{4}{25}=0.16\ \frac{gallons}{piece}

therefore

0.16 gallons of paint are used on each piece of furniture.

The answer lies between the whole numbers 0 and 1.

Solve<br> 4x + 1 = 2x -5
Jobisdone [24]

∑ Hey, ramosblan81 ⊃

Answer:

x = -3

Step-by-step explanation:

<u><em>⇒ Given:</em></u>

<em>4x + 1 = 2x -5</em>

<em />

<u><em>║ Solve ║:</em></u>

<em>4x + 1 = 2x -5</em>

<em>Subtracting 1 from both sides:</em>

<em>4x + 1 = 2x -5</em>

<em>4x + 1 - 1 = 2x -5 -1</em>

<em>4x = 2x - 6</em>

<em>Now subtracting 2x from both sides:</em>

<em>4x - 2x = 2x - 6 - 2x</em>

<em>2x = -6</em>

<em>Then divide both sides by 2</em>

<em>2x/2 = -6/2</em>

<em>x = -3</em>

<em />

<em>Thus, the answer is x = -3.</em>

<em />

<u><em>xcookiex12</em></u>

Can anyone help me with this, i’m so confused

z/y

Step-by-step explanation:

when dividing with exponents, you simply subtract the variables w exponents

y^5 - y^6 = y^-1 (which is equal to 1/y)

z^3 - z^2 = z^1 (which is equal to z/1)

1/y * z/1 = z/y
