the answer is D

Step-by-step explanation:

You would multiply the sales tax (0.06) to the total of the items bought then you would add that to the total amount of the items bought so 34.85+ 2.091 which is the answer of D

Answer:

x = -5

Step-by-step explanation:

77+66+x+42 = 180

x + 185 =180

x = -5

Step-by-step explanation:

Let say the unknown number we dont know is x

2x+4=6

2x=6-4

2x=2

x=2/2

x=1

So the unknown number is 1

Answer:

Answer:

Y= -x - 1

Step-by-step explanation:

Answer:

y= -x - 1

Step-by-step explanation:

i just got it right

Answer:

your answer is -1

Step-by-step explanation:

Answer:

a. x^2 - 1

b. x^2 - 6x + 9

c. [tex]\dfrac{3x + 1}{x^2 + x}[/tex]

Step-by-step explanation:

a.

(x + 1)(x - 1) =

= x^2 - x + x - 1

= x^2 - 1

b.

(x - 3)^2 =

= (x - 3)(x - 3)

= x^2 - 3x - 3x + 9

= x^2 - 6x + 9

c.

[tex] \dfrac{3 + \frac{1}{x}}{1 + x} = [/tex]

[tex] = \dfrac{x(3 + \frac{1}{x})}{x(1 + x)} [/tex]

[tex] = \dfrac{3x + 1}{x + x^2} [/tex]

[tex] = \dfrac{3x + 1}{x^2 + x} [/tex]

27

12x4=48

then 3+3+3=9 because its 3/4

then you add 12 because of the 1

then 48-21=27

Answer: its 27

4x-26=3x+4

4x=3x+30

x=30

they are vertical angles meaning they are equal

Answer:

3

y=(8x-8)3+7

y=24x-24+7

y=24x-17

17=24x

17/24=x

SO == x-17/24 y= 17

Step-by-step explanation:

NO and PQ are congruent segments (have the same length), and both have the same midpoint M.

NO ≅ PQ, given.

NM ≅ ½ NO, definition of midpoint.

PM ≅ ½ PQ, definition of midpoint.

PM ≅ ½ NO, substitution.

PM ≅ NM, substitution.

Answer:

x=5

Step-by-step explanation:

They are vertical angles, so they are equal.

22x+5=23x

minus 22x from each side

5=x

and you can switch it around :)

x=5

A number is :

[tex]x[/tex]

_________________________________

Three quarters of it means :

[tex] \frac{3}{4}x \\ [/tex]

_________________________________

Decrease by 20 means :

[tex] \frac{3}{4}x - 20 \\ [/tex]

_________________________________

Equals to 82 means :

[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]

_________________________________

What is that number ?

x asked so we must solve the above equation for x.

Let's do it....

[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]

Plus sides 20

[tex] \frac{3}{4}x = 82 + 20 \\ [/tex]

[tex] \frac{3}{4}x = 102 \\ [/tex]

Multiply sides by 4

[tex]3x = 102 \times 4[/tex]

Divided sides by 3

[tex]x = \frac{102 \times 4}{3} \\ [/tex]

[tex]x = \frac{102}{3} \times 4 \\ [/tex]

Simplify

[tex]x = 34 \times 4[/tex]

[tex]x = 136[/tex]

So that number is 136 .

I apologize for no work but that is what the answers are

Answer:

3.8 seconds

Step-by-step explanation:

Time taken to sort the mail is [tex]5[/tex] seconds

Let time taken to go from one mailbox to the next be [tex]x[/tex]

Distance between the mailboxes is [tex]100[/tex] ft

So, sorting the mail for one mailbox and going to the next will be done in [tex](5+x)[/tex] seconds

This will happen 19 times and 5 seconds will be needed to sort the mail for the last mail box. The carrier will have to deliver to all the 20 mailboxes in 10 minutes. So, the total time taken will be

[tex]19(5+x)+5=10\times 60\\\Rightarrow 19(5+x)=595\\\Rightarrow 5+x=\dfrac{595}{19}\\\Rightarrow x=\dfrac{595}{19}-5\\\Rightarrow x=\dfrac{500}{19}\ \text{s}[/tex]

Time taken to go from one mailbox to the other is [tex]\dfrac{500}{19}\ \text{s}[/tex]

Speed is given by

[tex]v=\dfrac{100}{\dfrac{500}{19}}\\\Rightarrow v=3.8\ \text{ft/s}[/tex]

The speed at which the carrier has to move from one mailbox to the next is 3.8 seconds.

Answer:

a. 8m

b. 7cm

Step-by-step explanation:

a. Area of a square is s², where s is the side length.

To find s:

s² = 64

s = √64

s = ±8

length cannot be negative, hence it is positive 8

b. Perimeter of a square is 4s = P, where P is the perimeter and s is the side length.

4s = 28

s = 7

Answer:

C

Step-by-step explanation:

the answer is 15. hope this helps
