can anybody help on this question ? please and thank you !!

Answer:

$56

Step-by-step explanation:

the equation is A=42+b

b=14 because Leila sells 14 books

substitute 14 in the equation: A=42+14

A=56

Answer:

She earns 1 dollar for each book sold

A = 42+B*1

A = 41+B

Let B = 14

A = 41+14

A = 56

x=-33+7y

then putting value of x

18(-33+7y)-77=1

-594+126y-77=1

-671+126y=1

126y=670

y=670/126

Answer:

26cm

Step-by-step explanation:

AO is half of the rectangle. if BD is the whole rectangle... AO (13) times 2 equals 26 cm = BD

Answer:

an = 5 − 3(n − 1)

Step-by-step explanation:

First term,a = 5

Second term = 2

Common difference,d = 2 - 5 = -3

nth term = a + d(n - 1)

= 5 -3(n - 1)

Check

When n = 2

2nd term = 5 - 3(2 - 1)

= 5 - 3(1)

=5 - 3

= 2

2nd term = 2

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:

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: [tex]15r^2-21r+5[/tex]

Step-by-step explanation:

Given: Perimeter of triangular garden = [tex]25r^2 - 9r + 14[/tex]

The sum of two sides of the garden = [tex]10r^2 + 12r + 9[/tex]

Perimeter is the sum of all sides of a triangle.

Third side = Perimeter of triangular garden - sum of two sides of the garden

[tex]=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5[/tex]

The expression represent the third side = [tex]15r^2-21r+5[/tex].

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

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: $2.40

Step-by-step explanation:

If Kevin gets 12 dollars for every 5 problems, we will need to divide 12 by 5 to find the unit rate; how much Kevin gets for each problem.

12 ÷ 5 = 2.4, and in dollars it is equal to $2.40. Because of this, Kevin is paid $2.40 for each problem he makes for the ST2 publishing Company.

Answer:

x = 125.44

Step-by-step explanation:

you multiply both side by 7

so 7 • 17.92 = 7 • x/7

125.44 = x

Answer:

x = 125.44

Step-by-step explanation:

multiply each side of the equation by 7

17.92(7) = [tex]\frac{x}{7}[/tex](7)

125.44 = 7x / 7

7x / 7 = 1x or x

x = 125.44

Answer:

45.

A=a+b/2  

2/h=7+11/2  

2·5=45

D) -3

because the number should be less than -2 and greater than -6

Answer:

Answer:

8. s(-2) = 3, s(0) = 2, s(4) = 0

Look at the table for each of the values of x in s(x) and see what the y-value is. For example, for s(-2) you look at what y is when x = -2. It would be y = 3.

9. when x = -4, so s(-4)

Look through the table to find the row where y = 4. x would be -4.

10. -1

You can see that each time x goes up by 2, y goes down by 1. This means that the next row would say x = 6 and y = -1. The predicted value of s(x) is -1.

Answer:

I think its BD/FG=AD/EH.

Answer:

x=8,y=-1

Step-by-step explanation:

x-2y=10

x=10+2y

10+2y+3y=5

5y=-5

y=-1

x-2(-1)=10

x=8

The solution to the system of equations x - 2y = 10 and x + 3y = 5 is x = 8 and y =-1

The system of equations is given as:

x - 2y = 10

x + 3y = 5

Subtract both equations

-2y - 3y = 10 - 5

Evaluate

-5y = 5

Divide both sides by -5

y = -1

Substitute y = -1 in x - 2y = 10

x - 2(-1) = 10

This gives

x + 2 = 10

Subtract 2 from both sides

x = 8

Hence, the solution to the equations is x = 8 and y =-1
