A store pays $147 for a skateboard. If the store marks it up 75%, then marks it down 22%. What is the new cost​

Answer:

18x^2 - 30x

Step-by-step explanation:

Distribution:

You just have to distribute 6x by each term in the parenthesis.

Equation: 6x(3x-5)

(You can also think of it as: 6x * 3x + 6x * -5)

18x^2 - 30x

This is as simplified as can it can be.

(You can’t add terms that have different variables, seeing as the first term has x^2 and the second one only has x).

Answer:

|8|a + |35|     or      = |-8|a+|-35_|

Step-by-step explanation:

8(a+5)=8•a+8•5

         =8a+35

         = |8|a + |35|     or      = |-8|a+|-35_|

Answer: 5x

Step-by-step explanation:

5x + 3x = 8x

Answer: Question

find the missing term in the equation below (?+5)+(3x-2)=8x+3

(5x+5)+(3x-2)=8x+3

5x+5+3x-2

5x+3x+5-2

8x+3

therefore, answer proved

Answer:

okay...... where is the question

Answer:

7 buses. 52÷ 8 = 6.5 so rounding up to 7

Answer:39?

Step-by-step explanation:

I would say 12 and 14 because if you were to evaluate that square root, you would get −13.0384048104 and that would lie between 12 and 14.

If I'm wrong, sorry.

Step-by-step explanation:

Median= n+1/2 ( if n is even )

So,

10+1/2=11/2=5.5

Therefore,

135 is your second answer

Spread of the data = in the above mentioned picture the wave given to find the spread of the data

Hope it helps

you do this 8 x 6 x 14 x 4 = 672

Answer:

D.) x2 + (y + 1)2 = 1

Step-by-step explanation:

No explanation needed just need to say something here.

Answer:

x2 + (y + 1)2 = 1

Step-by-step explanation:

Answer:

x=20 y=34

Step-by-step explanation:

x+14=2x-6

x=20

(20)+14=y

y=34

Answer:3.2

Step-by-step explanation:

3.2 because x =16/5=3 1/5=3.2

Answer:

It’s false

So 27.75 is your answer

Answer:

I'm pretty sure the answer is C

Answer:

m=0

Step-by-step explanation:

the formula given for slope (m) calculated from two points is given as (y2-y1)/(x2-x1)

we are given the points (10,3) and (2,3)

label the values of the points to use for the formula:

x1=10

y1=3

x2=2

y2=3

plug into the formula

m=(3-3)/(2-10)

subtract

m=0/-8

divide

m=0

therefore, the slope is 0

Hope this helps! :D

0/-8

i’m not very good at explaining but that is the answer ^^

Answer:

Tank 2 filling faster

Step-by-step explanation:

Tank 1 filling at 1 1/8 gallons per minute (3/4 ÷ 2/3)

Answer:

Answer

Step-by-step explanation:

The answer is d because if you at 17 to 197 you'll get 203

Answer:

y=x/3 - 4

Step-by-step explanation:

add x to get x to the other side

3y= x-12

divide by 3 on both sides to get y by itself y= x/3 - 4 is simplest form

Answer:

slope intercept form is y=mx+b

add x to both sides : 3y=x-12

divide by 3 on both sides : y=(1/3)x-4

nnnd i put both equations in desmos n they r the same :)

Answer:

8.7

Step-by-step explanation:

The answer is 8.7 because 280 centemiters converted into meters is 2.8 and 11.5-2.8=8.7

Answer:

The answer is 6m

Step-by-step explanation:

This is because the formulae used to find the area of a triangle is ½ multiplied by the base multiplied by the height.

Hope it helps:)

Answer:

Sample proportion ; phat

x / n

Step-by-step explanation:

The sample proportion may be explained as a proportional representation of part of the population or larger sample which have a certain character or exhibit a particular trait.

The sample proportion is expressed Mathematically as ;

phat = x / n

x = number of subjects with a specified characteristic ;

n = total sample size

For instance ;

The proportion of black balls in a sample of 100 balls is 15 ; the sample proportion of bla k balls will be :

phat = x / n = 15 / 100 = 0.15

Answer:

x = 30

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2.5}{5}[/tex] = [tex]\frac{1}{2}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = 30

Answer:

Step-by-step explanation:

Given function:

The x-coordinate of a quadratic function y = ax² + bx + c is determined by:

The given function has:

Find the value of b:

The function is:

The y-coordinate of the vertex is:

Answer:

Solution given:

y = -x² + bx + 3

we have

The x-coordinate of a quadratic function y = ax² + bx + c is determined by:

x = [tex] \frac{ - b}{2a} [/tex]

we have

x = 10, and a = -1

Substituting value of a in -b/2a

we get

b = 20

now

The y-coordinate of the vertex is:

y = -(10²) +20*10+ 3 = -100 + 200 + 3 = 103 is your answer.
