I ordered 4 new CD's by mail. Each CD costs the same amount and there was an additional $5 shipping charge that brought the total to $33. Write and solve the equation to find the cost of one CD.

Answer:

[tex] \frac{2 \times{x}^{2} }{3} = 8 \\ 2 {x}^{2} = 24 \\ {x}^{2} = 12 \\ x = 3.46[/tex]

Answer:

-10

Step-by-step explanation:

-5x - 1 = -10x - 51

Add 10x to both sides.

5x - 1 = -51

Add 1 to both sides.

5x = -50

Divide both sides by 5.

x = -10

I hope this helped! :)

Answer:$66.00

Step-by-step explanation:

first we need multiply :D I will use the formula I =prt

principal= $500

rate=3.3%

time= 4 years

but we need to convert the percent, 3.3%, to a decimal

3.3%=0.033 or .033

then we multiply

500 × 0.033 × 4 = 66 = $66.00

Answer:

a. x=57.6, y=44.8

Step-by-step explanation:

Named the angles, check the picture for that

<ABD+<ACD=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)

<CAB+<BDC=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)

therefore:

a. 3y+x-12=180.............. equ 1

2x+y+20=180.............equ 2

From equ 1

x+3y=180+12

x+3y=192...............equ 3

From equ 2

2x+y=180-20

2x+y=160.............equ 4

Equate equ 3 and equ 4

x+3y=192...............equ 3

2x+y=160.............equ 4

Using elimation method

x+3y=192...............equ 3

2x+y=160.............equ 4

Multiple equ 3 by 1 and equ 4 by 3

x+3y=192...............equ 3 ×1

2x+y=160.............equ 4 ×3

x+3y=192

6x+3y=480

Subtract

-5x+0=-288

-5x=-288

x=57.6................... Equ 5

Replace 57.6 for x in equ 3

x+3y=192...............equ 3

57.6+3y=192

3y=192-57.6

3y=134.4

y=44.8

B. <CAB= 2x=2×57.6=115.2

<ABD= 3y=3×44.8= 134.4

<ACD=x-12=57.6-12=45.6

<BDC=y+20=44.8+20=64.8

Answer:the nth term of the sequence, Tn= -3n +12

Step-by-step explanation:

The nth term of an arithmetic progression is given as

Tn=  a+ (n-1) d

where a= first term

and d = common difference

In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that  the number is decreasing by 3

The first term, a= 9

and common difference, d = -3

using our formulae

Tn=  a+ (n-1) d

Tn= 9 + ( n-1) -3

Tn=9- 3n+ 3

Tn= -3n +12

Answer:

(0, 3)

Step-by-step explanation:

The equation already shows the y-intercept (written as +3). The slope is -4x and the y-intercept is (0, 3).

Answer:

y=3

Step-by-step explanation:

Because we know x equals 0 we put that into the equation so then you have y=4(0)+3 you multiply 4 time 0 and get 0 so all you have left is 3.

Answer:

A formula for the nth term of the given sequence is:

[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]

Step-by-step explanation:

Given the sequence

36, -48, 64...

We know that a geometric sequence has a constant ratio r and is defined by

[tex]a_n=a_1\cdot r^{n-1}[/tex]

Compute the ratios of all the adjacent terms

[tex]\frac{-48}{36}=-\frac{4}{3},\:\quad \frac{64}{-48}=-\frac{4}{3}[/tex]

The ratio of all the adjacent terms is the same and equal to

[tex]r=-\frac{4}{3}[/tex]

Therefore, the given sequence is a geometric sequence.

As the first element of the sequence is

[tex]a_1=36[/tex]

so substituting [tex]a_1=36[/tex] and [tex]r=-\frac{4}{3}[/tex] in the nth term

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]

Therefore, a formula for the nth term of the given sequence is:

[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]

Answer:

1. 482

2. 60

HOPE THIS HELPS YOU

Answer

20. 470 = x - 12 (Solving for X: There was 482 pages before decreasing by 12)

21. 65 = x + 5  (Solving for X: There was 60 pages read before reading 5 more)

43% were from passing so 100% - 43% = 57% came by other means.

28 x 57% = 28 x 0.57 = 16

16 came from different means.

Answer: 35cm²

Step-by-step explanation:

This is a composite shape so break it down into its individual shapes and get their areas then add them up to find the shape's total area.

Area of Triangle:

= 1/2 * base * height

= 1/2 * 8 * 5.75

= 23 cm²

Base = 4 + 4 = 8cm

Area of the Trapezium

= (a + b) / 2 * height

a is top length

b is bottom length

= (4 + 8) / 2 * 2

= 12 cm²

Add them up:

= 23 + 12

= 35cm²

Answer:

Answer: 35cm²

Step-by-step explanation:

The equations of E and R are illustrations of cost and revenue functions

The equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p

The cost and the revenue functions are given as:

E = -20,000p + 90,000

R = -2,170p^2 + 87,000p

At the break even point, we have:

E = R

Substitute known values

-20,000p + 90,000 = -2,170p^2 + 87,000p

Hence, the equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p
