The answer is 45 because a object with 4 sides is equal to 360 degrees. If 45 is x you would add them together as 45+45+135+135=360

Simplify using the distributive property
ad-work [718]

Answer:

3/5 is the number that can be distributed across two terms inside parentheses.

you might not need it but:

x = 5

Step-by-step explanation:

<u>3/5(x - 10)</u> = 18 - 4x - 1

using distributive property, open the parentheses:

<u>3/5x - 6 </u>= 18 - 4x - 1

Simplify:

3/5x + 4x = 17 + 6

4⅗x = 23

x = 5

Paul purchased a used vehicle that depreciates under a straight-line method.
netineya [11]

Answer:

Option B. $900

Step-by-step explanation:

Let

y ----> the value of the car

x ----> the time in years

we know that

The linear function in slope intercept form is equal to

y=mx+b

where

m is the slope or the depreciation rate

b is the y-intercept or initial value of the car

we have

The y-intercept or initial value is equal to

b=\$5,000

y=mx+5,000

we have the ordered pair (5,500)

substitute the value of x and the value of y of the ordered pair in the linear equation and solve for m

500=m(5)+5,000

5m=500-5,000\\5m=-4,500\\m=-\$900\ per\ year

Is negative because is a decreasing function

The linear equation is equal to

y=-900x+5,000

therefore

It would depreciate $900 each year.

Please solve this question withvfull process i will wark as braineast a) After allowing 5 % discount on the marked price of a ra
schepotkina [342]

Answer:

Let the marked price be x

Discount % = 10%

Discount = 10\% \times x = 0.1x10%×x=0.1x

Cost after discount = x-0.1x = 0.9x

10%vat is charged on it

Cost including VAT = 0.9x+0.1(0.9x)=0.99x0.9x+0.1(0.9x)=0.99x

We are given that  it's price became rs 1672

So, 0.99x = 1672

x=\frac{1672}{0.99}x=0.991672

x=1688.88

Discount = 0.1x=0.1(1688.88)=168.888

Hence The discount

Choose the correct simplification of the expression (−2x + 8y)(9x − 3y).
Romashka-Z-Leto [24]
For these kinds of expressions use FOIL (first, outside, inside, last).

-2x • 9x = -18x^2
-2x • -3y = 6xy
8y • 9x = 72 xy
8y • -3y = -24y^2

Now combine them all:

-18x^2 + 78xy - 24y^2
