+3х2+3x2

What is that answer simplified?

Answer: x= 17°

Step-by-step explanation:

The two measures have to add up to 180 degrees.

(7x -1) + (5x -23) = 180    combine like terms on the left side

12x - 24 = 180 add 24 to both sides

      +24    +24

12x = 204     Divide both sides by 12

x = 17

Answer:

  see below

Step-by-step explanation:

The difference between start and end times is the duration in each case.

The earliest start time is the latest of the earliest finish times of all predecessor tasks. These are computed working left to right.

The latest finish time is the earliest of the latest start times of all successor tasks. These are computed working right to left.

Where earliest and latest times are the same, the task is on the critical path. (It has no slack time.)

The above computations have been built into the attached spreadsheet. Here, predecessors and successors are handled manually. In appropriate scheduling software, they would be handled automatically by the specification of the task relationships.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that the regular price for the specialty paper is

$6.88 per carton

and the company receives a discount of $1.75 per carton

this means that the company will pay  $6.88-$1.75 = $5.13 per carton

To calculate the cost of the supply for 24 cartons we have

24*5.13= $123.12

the cost of the supply is $123.12

alternatively we can also calculate the percentage discount as

Actual cost of 24 cartons= 24*6.88= $165.12

Discount= $6.88-$1.75 = $5.13 per carton

%discount= 1.75/6.88= 0.2543

= 25.43%

The price after discount is

=$165.12*(1-0.2543)

=$165.12*0.7456

= $123.12

Answer:

= 32

Step-by-step explanation:

= 8 [ 20 - { (9-5) }² ]

= 8 [ 20 - { (4) }² ]

= 8 [ 20 - 16 ]

= 8 [ 4 ]

= 32

Answer:

P(x) = 3x - 150

Step-by-step explanation:

Step-by-step explanation:

P(x) = R(x) - C(x)

Given:

R(x) = 5x

C(x) = 2x + 150

P(x) = 5x -(2x+150)

P(x) = 5x - 2x -150

P(x) = 3x - 150 <- Answer

Answer:

The profit function is P(x) = 3x-150

Step-by-step explanation:

Reason is R(x) = 5x

C(x)= 2x + 150

Plugin to P(x) = R(x) - C(x)

P(x) = 5x - (2x+150)

P(x) = 5x - 2x-150

P(x) = 3x-150

Answer:

Step-by-step explanation:

First you do the parentheses so the -3 x 8n= -24 and -3 x -5= 15

so it will look like this. -24n+15-2n=8n-21

Now combine like terms the -24n-2n.

-26n+15=8n-21 now subtract 8n now it will look like this

-34n+15=-21 now -15 from -21

-34n=-36

now if you want n by its self divide -34 and -36

Answer:

each will get 11 Apple's

Step-by-step explanation:

divide it by 792 ÷72

11.

Answer:

11 apples per student

Step-by-step explanation:

it is a simple division task and you can apply two methods.

Method one

[tex]\frac{792 apples}{72 students}[/tex] =11 Apples per Student

Method two

if 11 students shares 792 apples

1 students gets __x__ apples.

cross multiply

x = [tex]\frac{(792 apples * 1 students)}{11 students}[/tex] = 11 Apples

Answer: 36 miles.

Step-by-step explanation: Ratio of 1 to 0.6 means 1:0.6 or [tex]\frac{1}{0.6}[/tex].

So, if to Moncton is 60km:

[tex]\frac{1}{0.6}=\frac{60}{y}[/tex]

[tex]y=60.0.6[/tex]

y = 36

To Moncton, it is 36 miles.

Answer:

The radian measure of the central angle of the given circle is [tex]\frac{7}{19} rad[/tex]

Step-by-step explanation:

The radian measure of the central angle θ of a circle of radius r that intercepts an arc of length s can be calculated from the formula given below

s =rθ

where s is the length of arc

r is radius of the circle

and θ is the central angle in rad (radian)

From s = rθ, Then

θ = s / r

From the question,

Radius r = 19 feet

and Arc length s = 7 feet

Hence,

θ = s / r becomes

θ = 7 / 19

∴ θ [tex]= \frac{7}{19} rad[/tex]

This means the radian measure of the central angle of the given circle is [tex]\frac{7}{19} rad[/tex]

Answer:

[tex]y=8[/tex]

RS: 77

ST: 46

Step-by-step explanation:

We know that RS and ST together make the line RT. This means the sum of their lengths will be equal to RT.

Since RT is 123, we can create the equation [tex]9y+5+5y+6=123[/tex].

Combining like terms gets us [tex]14y+11=123[/tex]

We can now solve for y by isolating the variable on one side of the equation.

[tex]14y + 11 - 11 = 123-11\\\\14y=112\\\\14y\div14 = 112\div14\\\\y=8[/tex]

Now we know the value of y. We can now substitute this into the expressions for RS and ST to find their values.

RS = [tex]9y+5\\\\(9\cdot8)+5\\\\72+5\\\\77[/tex]

ST = [tex]5y+6\\\\(5\cdot8)+6\\\\40+6\\\\46[/tex]

We can confirm this is correct because [tex]46+77=123[/tex].

Hope this helped!

Answer:

13. 68

14. y = 0.50x + 8

15. y = 25x - 15

16. y = 7x - 1

17. [tex]a_n = 4 + 6(n-1)[/tex]

Step-by-step explanation:

13. f(3) means plug in 3 for x.

f(3) = 7(3)² + 5 = 7(9) + 5 = 63 + 5 = 68

14. Write out what you know. 0.50 inches per hour is the rate of snowfall, or your m, or your slope. m = 0.50. If x is hours passed and y is inches of snowfall, then you also know that at x = 4, y is 10. Plug these into the standard linear formula: y = mx + b => 10 = 0.50(4) + b

Solve for b:

10 = 0.50(4) + b

10 = 2 + b

b = 8

Remember, x and y are variables, not constants, but m and b are always the same for some given function. So your answer is y = 0.50x + 8

15. Write out what you know. If x is hours passed and y is distance from home in miles, then we need to find the slope and y-intercept using what you're given. How do you find the slope? Use this: [tex]m (or slope) = \frac{y_2 - y_1}{x_2 - x_1}[/tex].

You have two points given: (3, 60) and (7, 160). So [tex]m = \frac{160-60}{7-3} = \frac{100}{4} = 25[/tex]

Now, just use either of these points to find b, or your y-intercept.

y = mx + b

Let's just use (3, 60); either one would work though.

[tex]60 = 25(3) + b[/tex]

60 = 75 + b

b = -15

To make the equation, use the values for m and b that you found.

m = 25 and b = -15, so y = 25x - 15

16. In y = mx + b, b is the y-intercept, but it's also how much the graph shifts up or down from its "original" position. I don't really want to explain this, but you can experiment with y = x + something (like try y = x + 1, y = x - 1, y = x, y = x + 3) and you'll see the pattern of what I'm talking about. To move y = 7x + 3 down 4 units, just subtract 4 from 3 to get -1: you will get y = 7x - 1.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = - 10}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ \frac{5}{6} = \frac{x - 10}{3x + 6} }[/tex]

Apply cross product property

⇒[tex] \sf{5(3x + 6) = 6( x - 10)}[/tex]

Distribute 5 through the parentheses

⇒[tex] \sf{15x + 30 = 6( x - 10)}[/tex]

Distribute 6 through the parentheses

⇒[tex] \sf{15x + 30 = 6x - 60}[/tex]

Move 6x to left hand side and change it's sign

⇒[tex] \sf{15x - 6x + 30 = - 60}[/tex]

Collect like terms

⇒[tex] \sf{9x + 30 = - 60}[/tex]

Move 30 to right hand side and change it's sign

⇒[tex] \sf{9x = - 60 - 30}[/tex]

Calculate

⇒[tex] \sf{9x = - 90}[/tex]

Divide both sides of the equation by 9

⇒[tex] \sf{ \frac{9x}{9} = \frac{ - 90}{9} }[/tex]

Calculate

⇒[tex] \sf{x = - 10}[/tex]

Answer:

Rational number

Step-by-step explanation:

Answer:

Rational number

Step-by-step explanation:

Answer:

The us based motorcycle manufacturer says that it expects to build 140,000 motorcycles this year up from 126,000 last year.

This means the increased production is

144,000 - 126,000 = 18,000

The percentage change in production can

be found using the formula as listed below

PERCENTAGE INCREASE = change / initial × 100

Substitute the values we get

18,000/126,000 × 100

14.28 = percentage increase

Answer:

Step-by-step explanation:

We begin by calculating the amount after the 25% discount

= regular price*0.75

=£160*0.75

=$120

We then continue by calculating the the amount that must be paid when 20% VAT is added

= 120*1.20

= $144

Now Tara is going to spend 7 nights

Hence she will have to pay

144*7= $1008
