Answer

9 - 2x

Step-by-step explanation:

since there is no equal symbol in this equation, you can only simplify it.

[tex]20-2x-11[/tex]

first combine like terms:

[tex](20-11)-2x[/tex]

then subtract 11 from 20, this will give you 20-2x-11 in its simplest form.

Answer: The first 6 terms are = 8, 10, 12,14,16,18

Step-by-step explanation:

The NTH term of an Arithmetic Sequence is given as

an = a1 + (n - 1 ) d

where a1 = First term  given as 8 and

d=  common difference given as 2

Therefore  We have that

the first term

an = a1 + (n - 1 ) d = 8+(1-1) 2

a1= 8

second term=

an = a1 + (n - 1 ) d= a2= 8 + (2-1) 2

= 8+ 2(1) = 10

3rd term

an = a1 + (n - 1 ) d= a3= 8 + (3-1) 2

= 8+ 2(2)= 8 + 4=12

4th term

an = a1 + (n - 1 ) d= a4= 8 + (4-1) 2

= 8+ 2(3)= 8+6=14

5th term

an = a1 + (n - 1 ) d= a5= 8 + (5-1) 2

= 8+ 2(4)=8+ 8=16

6th term

an = a1 + (n - 1 ) d= a6= 8 + (6-1) 2

= 8+ 2(5)=8 +10 =18

Answer:

5 6 + 4 2

Step-by-step explanation:

1 0 − 8 ( − 7 - 4 )

1 0 + 5 6 + 3 2

1 0 + 5 6 + 3 2

4 2 + 5 6

4 2 + 5 6

Answer:

The unit price is $3.06

Step-by-step explanation:

Unit price is how much I unit of something costs. Therefore in order to find the unit price you just divide the total price by the number of units (in our case 5 folders). And so we get...

$15.30 / 5 = $3.06

Answer:

2.08secs

Step-by-step explanation:

Given the equation modeled by the height as h=-121t^2 +504t

The velocity of the object at the max height is zero, hence;

v = dh/dt = 0

dh/dt = -2(121)t + 504

dh/dt = -242t + 504

0 = -242t + 504

242t = 504

t = 504/242

t = 2.08secs

Hence the projectile reaches its maximum height after 2.08secs

How many questions are there?

Answer:

A=73

Step-by-step explanation:

sum of interior angles is (n-2)*180

5 sides, so (5-2)*180 = 3x180=540

sum of current interior angles (118+96+115+104)=433

subtract 540-433=107

This is NOT "A", this is your final interior measurement.

To get "A", take 180-107=73

A=73 degrees

Answer:

16

Step-by-step explanation:

There are 2 different ways to solve this

1) The bigger triangle is 4 times bigger than the smaller one

5 x 4 = 20

3 x 4 = 12

From this method you can see they all connect so you take the smaller triangles value of 4 and multiply it by 4

4 x 4 = 16

2) Pythagorean theorem and reorganizing the formula so that the a value is found

[tex]a = \sqrt{c^{2} -b^{2} }[/tex]

Answer:

a

Step-by-step explanation:

To evaluate f(4), substitute x = 4 into f(x), that is

===========================================================

Explanation:

Consider triangle ABC. The vertex points are at A,B,C. These represent the three cities in which the three different daughters live. Constructing the circumcenter will produce a circle such that all three points A,B,C are on that circle. Let's say that D is the center of that circle.

This means that AD, BD, CD are all radii of this same circle. Radii of the same circle are the same length, which is why point D is equally distant from A,B,C. If the mother lives at point D, then she will travel the same distance to visit any three of her daughters. See the note below.

To construct the circumcenter, we form perpendicular bisectors to segments AB, BC and AC. Technically you only need two of them. All three of these perpendicular bisectors intersect at point D.

Note: Keep in mind that roads aren't completely straight, so that means we'll have to factor in the curvature of each road. But to keep things simple, we assume each road is a straight line segment.

Answer:

Range = 5 - 29

Step-by-step explanation:

a + b > c

a+c > b

c+b > a  

so

17+ 12 > c  ,,,,,,,,,,,,,,,,,,,,,,,,,,,, so it should be lesser than 17+12 which is 29

17 +c > 12    ,,,,,,,,,,,,,,,,,,,,,,,,, and it should be greater than 17- 12 = 5  

c+12 > 17 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, same here,  it should be greater than 17- 12 = 5  

So the range is ,

17 + 12

to

17-12

whcih is -   (5 to 29)

I hope I am right!!!

Answer:

28 hats

Step-by-step explanation:

We can solve this using a system of equations:

14.95s + 12.95h = 1588.50

s + h = 110

Let's isolate the shirt variable in the second equation:

s + h = 110

s = -h + 110

Now that we have isolated s we can plug it back into the first equation:

14.95(-h + 110) + 12.95h = 1588.50

Solve for h

-14.95h + 1644.5 + 12.95h = 1588.50

-2h + 1644.5 = 1588.50

-2h = -56

h = 28

The football team sold a total of 28 hats.

Hope this helps!!

- Kay :)

The number of hats did they sell should be considered as the 28 hats when the received amount is given.

Since

The football team had a fundraiser .

They received $1588.50 from the sale of 110 shirts and hats .

shirts sold for 14.95 each. hats sold for 12.95 each .

So, the following equations are applied

14.95s + 12.95h = 1588.50

s + h = 110

We can write like

s = -h + 110

Now

14.95(-h + 110) + 12.95h = 1588.50

-14.95h + 1644.5 + 12.95h = 1588.50

-2h + 1644.5 = 1588.50

-2h = -56

h = 28

Hence, The football team sold a total of 28 hats.
