(10x -20) (6x + 8)° what is the value of x​

Mathematics
1 answer:
Hoochie [10]2 years ago

Answer:

X=12

Step-by-step explanation:

Add the two equations together and equate them to 180 due to the geometrical reason that angles on a straight line add up to 180.

10X-20+6X+8=180 (collect like terms)

10X+6X=180-8+20

16X=192 (Divide both sides by 16)

X=12

Hope that helps :)

Answer:

Hey dude!

The answer is

area of triangle AED= \frac{1}{2} AE x DE

How I got this answer:-

Area of a triangle is \frac{1}{2} base x altitude.

Here, the base of the triangle is DE

And its altitude is AE

Hence, the area would be:-

\frac{1}{2} AE x DE

NikAS [45]

Answer:

17. a)

Step-by-step explanation:

17.

f(x) =x/2, then f(x-3)=(x-3)/2

x=3, f(x-3)=f(3-3)=f(0)=0 (values in table)

f(x-3)+3=0+3=3

18.

f(x) =x/2

f(x-2) for x=5 is f(5-2)=f(3)=3/2

f(x-2)+5=f(3)+5=3/2+5=3/2+10/2=13/2

For this item, any answers that are not whole numbers should be entered as decimals, rounded to the hundredth. Marissa's Fashion
trasher [3.6K]

You know that ...

... total cost = (marked-up price) + 6.25% × (marked-up price)

... $90.10 = (marked-up price) × 1.0625

Solving for (marked-up price) gives

... marked-up price = $90.10/1.0625 = $84.80

<u>Markup</u>

You also know that

... marked-up price = cost + markup

... $84.80 = $50.88 + markup

... $33.92 = markup . . . . . . . . . . . subtract $50.88

The percentage of markup can be figured a couple of different ways. It is easy to add a percentage to the cost price of an article, because the cost is generally right in front of the storekeeper when the article is received and prices are being marked. However, many accountants are interested in the percentage of the selling price that is available for overhead and profit, so they are interested in the markup as a percentage of selling price. The question here is non-specific as to the base to be used for figuring the percentage of markup.

The markup as a percentage of cost is

... $33.92/$50.88 × 100% = 66.67%

The markup as a percentage of selling price is

... $33.92/$84.80 × 100% = 40%
