Need help as soon as possible pls!!!!!

Answer:

i finished on the other question yw

Step-by-step explanation:

also not sure if you wanted the values for n

edit:

7. n/2 = 16

8. 2n + 4 = 52

9. 2(n + 5) = 17

10. 3n - 12 = 5

Answer:

7. 32

8. 24

9. 3.5

10. 5.6

Step-by-step explanation:

7. write the equation: n/2=16. Cross multiply.

8. write the equation: 52= 4+2n. Move 4 to the other side and subtract from 52: 48= 2n. Divide both sides by 2.

9. write the equation: 2(5+n)=17. Use the distributive property. Move 10 to the other side and subtract from 17: 2n=7. Divide both sides by 2.

10. write the equation 3n-12=5. move -12 over and add to 5: 3n=17. Divide both sides by 3.

Answer: 1/2 < 0.65 < 2/3 < 6.5

Step-by-step explanation:

Given information

0.65, 6.5, 2/3, 1/2

Convert fractions into decimals

0.65 = 0.65

6.5 = 6.5

2/3 = 0.67 (Rounded to hundredth place)

1/2 = 0.5

Arrange decimals from least to greatest

0.5 < 0.65 < 0.67 < 6.5

Convert terms back to the given form

1/2 < 0.65 < 2/3 < 6.5

B on edge 2022

Step-by-step explanation:

Answer:

x = -15

Step-by-step explanation:

Subtract x on both sides

x + 5 = -10

Subtract 5 on both sides

x = -15

Check work:

2(-15) + 5 = -15 - 10

-30 + 5 = -25

-25 = -25

Answer:

6.3 cm

Step-by-step explanation:

The distance from each centimeter is divided into 10 parts.  Point A starts at 0 and goes until right before 6.5.  The big line between each whole number signifies that you are halfway through the centimeter.  As you can see, point B is right before a big line, so can't be bigger than 6.5 nor equal.  The only option that fits this is 6.3 cm

The answer is 6.3 cm

Step-by-step explanation:

Important fact: much as I hate to admit it, in all professional sports, there is no team that has made as many appearances in the sports final as the Canadiens.

The ratio you want is 10/32 = 5/16.

The ratio means that for every 5 appearances the rangers made, the Canadiens made 16 appearances.

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

Work Shown:

C = 2*pi*r .... circumference equation

6pi = 2pi*r .... replace C with the given circle perimeter

6 = 2r .... divide both sides by pi, they cancel

6/2 = r

3 = r

r = 3 ... is the radius

------------

A = pi*r^2 .... area of circle equation

A = pi*3^2

A = pi*9

A = 9pi .... which points to choice B as the final answer

Answer:

2/18, or 1/9

Step-by-step explanation:

Lets start by finding out how many red, glass marbles there are.

Half of the red marbles of glass, and there are four red marbles. All we need to do is divide 4 by 2.

4/2=2

There are two glass marbles.

Now we just need to add the number of red marbles to yellow marbles. That would be 14+4, which is 18.

In conclusion, there are 2 red marbles, and 18 marbles in total, so it would be 2/18. Simplified, it would be 1/9.

3(7+4)^2-14÷7

PEMDAS says parentheses first

3(11)^2-14÷7

Then exponents

3(121)-14÷7

Then multiply from left to right

363 -14÷7

363 -2

[tex] {(x - 7)}^{2} \\ = {x}^{2} - 2 \times x \times 7 + {7}^{2} \\ = {x}^{2} - 14x + 49 \\ thank \: you[/tex]

Step-by-step explanation:

( x - 7)^2 is the same as :

( x - 7)* ( x - 7)

x ( x - 7) - 7(x - 7)

x² - 7x - 7x + 49

x² - 14x + 49

: 2(2x-7)+2(4x+3)=112

Step-by-step explanation:

Answer: Third Choice. 112 = 2 (2x - 7) + 2 (4x + 3)

Concept:

Here, we need to know how to find the perimeter of a rectangle.

Perimeter (rectangle) = 2l + 2w

l = length

w = width

Solve:

Given information

l = 2x - 7

w = 4x + 3

Perimeter = 112 cm

Given expression

Perimeter = 2l + 2w

Substitute values into the expression

[tex]\boxed{112 = 2 (2x - 7) + 2 (4x + 3)}[/tex]

Expand parentheses

112 = 4x - 14 + 8x + 6

Combine like terms

112 = (4x + 8x) + (6 - 14)

112 = 12x - 8

Add 8 on both sides

112 + 8 - 12x - 8 + 8

120 = 12x

Divide 12 on both sides

120 / 12 = 12x / 12

[tex]\boxed{x=10}[/tex]

Answer:

a.

MP3 player: 88%

Video game player: 92%

b.

MP3 player: 75 minutes

Video game player: 67 minutes

Step-by-step explanation:

a.

MP3 player

- Already has 40%

- Each 15 minutes additional 12%

--> An hour = (60/15)*12 = 48 (%)

--> After an hour charged = 40 + 48 = 88%

Video game player

- Already has 20%

- Each 10 minutes additional 12%

--> An hour = (60/10)*12 = 72 (%)

--> After an hour charged = 20 + 72 = 92 (%)

b. To charges 100 minutes:

MP3 player

100 = 40 + ((x/15*12)

--> x = 75 (minutes)

Video game player

100 = 20 + ((x/10*12)

--> x = 67 (minutes)

Exit for free stone

Distance from midtown to free stone

The distance from Midtown to Freestone is 26mi.

The Distance is defined as the product of the speed and time.

Given data as:

Exit for Midtown = 17 mi

Exit for Roseville =  35 mi

Exit for Edgewood = 51 mi

Exit for freestone = (35+51)/2

Exit for freestone = 86/2

Exit for freestone = 43mi

Distance from Midtown to Freestone = Exit for freestone - Exit for Midtown

Distance from Midtown to Freestone = 43 - 17

Distance from Midtown to Freestone = 26mi

Hence, the distance from Midtown to Freestone is 26mi.

Answer:

∠ ABC = 127°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ ABC is an exterior angle of the triangle , then

∠ ABC = ∠ BDC + ∠BCD = 60° + 67° = 127°

We know that we have a triangle and we want to find the value of its angle which will be given by  53°.

We know that the sum of all the interior angles of a triangle must equal 180 degrees, so we find then:

[tex]ABC=180[/tex]

Now making the sum of the angles already known and equating to 180, we find that:

[tex]180=67+60+x\\x=180-127\\x= 53[/tex]
