20% of 65 = 65 * 1/5, which is 13. so 20% of 65 is $13. so a discount of 20% = 65-13 which is $52

Solve for x X - 1/2 (8 - x) = x + 3(4 - x) - x<br> A) -32/9<br> B) -9/32<br> C) 32/9<br> D) 9/32

Option C

$x = \frac{32}{9}$

<em><u>Solution:</u></em>

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

We have to solve for "x"

From given,

$x - \frac{1}{2} \times (8 - x) = x + 3(4 - x) - x$

Solve for brackets

Use distributive property

a(b + c) = ab + ac

Therefore,

$x - 4 + \frac{x}{2} = x + 12 - 3x - x$

Combine the constants

$x + \frac{x}{2} = x - x - 3x + 12 + 4\\\\x + \frac{x}{2} = -3x + 16$

Move the variables to left side of equation

$x + \frac{x}{2} + 3x = 16$

Combine the like terms

$2x + x + 6x = 32\\\\9x = 32\\\\x = \frac{32}{9}$

Thus option C is correct

Which student correctly used guess and check to determine the unknown number?

Alenkasestr [34]

<h2>Explanation:</h2><h2></h2>

Hello! Remember you need to write complete questions in order to get good and exact answers. Here we know nothing about the students so I can only help you providing the correct steps to find <em>the product of a number and eight is 104:</em>

<em />

Let that number be $n$ , then the statement can be written in a mathematical language as follows:

$n\times 8=104 \\ \\ \\ \text{Dividing both sides by 8:} \\ \\ \frac{n\times 8}{8}=\frac{104}{8} \\ \\ \boxed{n=13}$

Finally, <em>the unknown number is 13</em>

joey can paint a room in 2 hours and chelsea can paint the same room in 3 hours. if they work together how long would it take to

JulijaS [17]

Answer:

$1.2\ hours$

Step-by-step explanation:

we know that

<em>Joey can paint a room in 2 hours</em>

That means

Joey can paint the 100% of the room-------> 2 hours

In 1 hour ------> can paint 100%/2=50%

<em>Chelsea can paint a room in 3 hours</em>

That means

C<em>helsea</em> can paint the 100% of the room-------> 3 hours

In 1 hour ------> can paint (100%/3)=33.33%

therefore

Joey and Chelsea in 1 hour can paint -----> 50%+33.33%=83.33%

by proportion

$\frac{1}{83.33}\frac{hour}{\%} =\frac{x}{100}\frac{hour}{\%}\\ \\x=100/83.33\\ \\ x=1.2\ hours$

12. The white triangle drawn on the road sign in the picture has a height of 8" and a base of 5". Which formula would be correct

nevsk [136]

Step-by-step explanation:

I think you did not copy the correct information of your answer options here.

because, as you wrote the 4 options, none of them are correct.

remember, the area of a triangle is base times height divided by 2

A = (b × h) / 2

given the numbers in the problem statement

b = 5, h = 8

A = (5 × 8) / 2 = 40 / 2 = 20

you need to pick the answer option in your original document that would lead to 20.

none of the 4 options you gave me here would result in 20. so, there must be something wrong with them.
