Can someone help me with this?

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:

13.64

Step-by-step explanation:

it's because it's basically the same size as 12.3 but a bit bigger. it cant be 18.2 because that would be too big and it cant be 6.4 cause its too small and so is 10.79.

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) A = 36π in² ≈ 113.09 in²

b)  $0.98 per slice

c) $0.09 per square inch

Step-by-step explanation:

a) area = πr²

    r= diameter/2 = 12/2 = 6

    A = π(6)²

    A = 36π in² ≈ 113.09 in²

b) s = price per slice

   s = 9.75 ÷ 10

   s = $0.975 ≈ $0.98

c) price per square inch = price ÷ area

   = 9.75 ÷ 113.09

   = $0.086 ≈ $0.09 per square inch

Answer:

A=7 1/3 < 7.663

Step-by-step explanation:

A=7 1/3 <7.663

The coordinates appear kinda wonky on my screen but are these the correct coordinates? (4,-8) and (-4,2)

What you will need is the mid-point formula.

The midpoint formula is:

(x1 + x2)/2, (y1 + y2)/2

x1 = 4, x2 = -4, y1 = -8, y2 = 2

We just need to plug in the known values and solve

(4 + -4)/2, (-8+2)/2

0/2, -6/2

(0,-3)

The answer is (0,-3)

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.

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:

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:

we conclude that:

Step-by-step explanation:

Given

u = {1,2,3,4,5,6,7,8,9, 10}

X= {1,2,4,6,7,8,9}

Y= {1,2,3,4,7,9)

Z= {2,3,4,7,9)

To determine

X∩Y∩Z = ?

We know that the intersection of three given sets represents the largest set which consists of all the elements that are common to all the sets.

The intersection of sets is denoted by the symbol '∩'.

Thus,

X= {1,2,4,6,7,8,9}

Y= {1,2,3,4,7,9)

Z= {2,3,4,7,9)

X∩Y∩Z = {2, 4, 7, 9}

Therefore, we conclude that:
