Answer:

n =1.78

Step-by-step explanation:

2(5n-6)

2(n+1)

10n-12+4n+2=15

14n-10=15

subtract both sides by 10

14n=25

25/14

n=n =1.78571428571

Step-by-step explanation:

Answer:

L=18.1, W=11.0

Step-by-step explanation:

Answer:

12 for the first one and twelve for the second one

Step-by-step explanation:

i think you can divide for the first one and second one if you divide 240÷20 you will get twelve and if you divide 180÷15 you will get 12

Answer:

9 x 5 = 45

Step-by-step explanation:

Answer:

im going to say its B

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

All you gotta do is take each angle and subtract it from 180. Jus learned dis in geometry.

180-133= 47

180-108=72

180-119=61

Answer:

B. 89

Step-by-step explanation:

LOE + EOV = LOV,

becomes

[tex]7x+12+4x+9=142\\11x+21=142\\11x=121\\x = 11[/tex]

LOE = 7x + 12, so:

[tex]7 * 11 + 12\\77 + 12\\89[/tex]

The thing before the square root means that the answer can be positive and negative.

Answer:

  (x, y) = (0, -6)

Step-by-step explanation:

Substitute for y in the second equation:

  2x -4(8x -6) = 24

  2x -32x +24 = 24

  -30x = 0

  x = 0

  y = 8·0 -6 = -6

The solution is (x, y) = (0, -6).

(b-7)m=r

Use the distributive property to multiply b-7 by m.

bm-7m=r

Add 7m to both sides.

bm=r+7m

The equation is in standard form.

mb=7m+r

Divide both sides by m.

mb/m = 7m+r/m

Dividing by m undoes the multiplication by m.

b= 7m+r/m

Divide r+7m by m.

b= r/m+7

Answer:

The closest amount paid is $23

Step-by-step explanation:

Given

[tex]Price = \$32[/tex]

[tex]Mark\ down = 20\%[/tex]

Amount = 10% of Marked down price

Required

Determine the amount paid

First, we calculate the marked down price P2:

[tex]P_2 = Price(1 - Mark\ down)[/tex]

Substitute values for Price and Mark down

[tex]P_2 = \$32 * (1 - 20\%)[/tex]

Express percentage as decimal

[tex]P_2 = \$32 * (1 - 0.20)[/tex]

[tex]P_2 = \$32 * (0.80)[/tex]

Remove bracket

[tex]P_2 = \$32 * 0.80[/tex]

[tex]P_2 = \$25.6[/tex]

The payable amount is 10% off the marked down price,

This is calculated as:

[tex]Amount = P_2 - P_2 * 10\%[/tex]

Substitute $25.6 for P2

[tex]Amount = \$25.6 - \$25.6* 10\%[/tex]

Express percentage as decimal

[tex]Amount = \$25.6 - \$25.6* 0.10[/tex]

[tex]Amount = \$25.6 - \$2.56[/tex]

[tex]Amount = \$23.04[/tex]

The closest amount paid is $23

Answer:

52%

Step-by-step explanation:

13×4= 52%

You just multiply by 4 to get the percentage

Answer:

20x = -58 - 2y( Ans~ x= -29/11)

17x = -49 - 2y (Ans~ x = -49/19)

Step-by-step explanation:

(1) 20x = -58 2x

   20x + 2x = -58

   22x = -58

   x = -29/11

(2) 17x = -49 - 2x

   17x + 2x = -49

   19x = -49

   x = -49/19

U WELCOME!!

Answer:

y=1

x=-3

Step-by-step explanation:

20x=-58-2y

20x/20=(-58-2y)/20

x=(-58-2y)/20

17x=-49-2y

17x/17=(-49-2y)/17

x=(-49-2y)/17

(-58-2y)/20=(-49-2y)/17

17(-58-2y)=20(-49-2y)

-986-34y=-980-40y

add 40y to both sides

6y-986=-980

add 986 to both sides

6y=6

divide both sides by 6

y=1

substitute

20x=-58-2(1)

20x=-60

x=-3

Proof: (substituting x & y values in original equations)

20(-3)=-58-2(1)

-60=-60

17(-3)=-49-2(1)

-51=-51

Answer: a glycoprotein that protrudes from the envelope of some viruses (such as a coronavirus) and facilitates entry of the virion into a host cell by binding to a receptor on the surface of a host cell followed by fusion of the viral and host cell membranes

Answer:

x = 8

Step-by-step explanation:

✔️Area of the square = s²

Where,

s = (2x - 4)

Area = (2x - 4)² = (2x - 4)(2x - 4) = 2x(2x - 4) -4(2x - 4)

= 4x² - 8x - 8x + 16

Area of square = 4x² - 16x + 16

Area of rectangle = L × W = (3x - 6) × x

= 3x² - 6x

✔️Since both have the same area, therefore,

4x² - 16x + 16 = 3x² - 6x

Collect like terms

4x² - 3x² - 16x + 6x + 16 = 0

x² - 10x + 16 = 0

Factorize

x² - 2x - 8x + 16 = 0

x(x - 2) -8(x - 2) = 0

(x - 2)(x - 8) = 0

(x - 2) = 0 or (x - 8) = 0

x = 2 or x = 8

If we plug in x = 2 into any of the given side length, we would have 0. (i.e. 2x - 4 = 2*2 - 4 = 0)

So the value of x cannot be 2 because the length of any of the shape cannot be 0.

So therefore, the value of x = 8

Answer:

Mean of M = 0.794

Standard Error = 0.013875

Step-by-step explanation:

Given that :

Sample size, n = 64

Mean percentage accuracy, μ = 0.794

Standard deviation, σ = 0.1110

Since the distribution of scores is normal ;

Sample mean, m ~ μ

Hence, m ~ 0.794

The sample sta dard deviation of standard error ~ σ/sqrt(n)

Standard Error = 0.1110 / sqrt(64)

Standard Error = 0.1110 / 8

Standard Error = 0.013875

Answer:

8.8= slope=1/3

y intercept=4/3

X intercept= -4

8.9 slope=1

Y intercept= 2

X intercept= -2

Step-by-step explanation:

compare the equation with the standard equation Y= MX + C

where M is the slope

to find Y intercept substitute the value of x as 0

to find X intercept substitute the value of Y as 0

Answer:

Your image is cut off, can you provide a better one so I can try to answer it?

Step-by-step explanation:

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

Work Shown:

(f + g)(x) = f(x) + g(x)

(f + g)(x) = x^2+x+1 + g(x) ............... plug in f(x) = x^2+x+1

(f + g)(x) = x^2+x+1 + x^2-9 ........... plug in g(x) = x^2-9

(f + g)(x) = (x^2+x^2)+x+(1-9)

(f + g)(x) = 2x^2+x-8
