PLS HELP

Answer:

ive tried working it out and i couldnt seem to get it but my best guess would be C OR B

Step-by-step explanation:

(3x + 1) (x - 2)

= 3x(x - 2) + 1(x - 2)

= 3x² - 6x + x - 2

= 3x² - 5x - 2

Answer:

y=−2x−15

Answer:

It will take 40 minutes for me to make the 360 wraps that I need.

9x ≥ 360 ⇒ x ≥ 40

Step-by-step explanation:

I have to make at least 360 wraps for a party.

I can make 9 wraps per minute.

So, it will take  minutes for me to make the 360 wraps that I need.

If I work for x minutes to make wraps, then I will be able to make 9x wraps.

So, the inequality that models the given condition is

9x ≥ 360

⇒ x ≥ 40 {Dividing both sides by 9}

Therefore, I need to work at least 40 minutes to reach my goal. (Answer)

the answer is 12 :)))))

Answer:

33/40

Step-by-step explanation:

cross multiply

5 x 5 = 25

8 x 1 = 8

25 + 8 = 33 (our numerator)

8 x 5 = 40 (our least common denominator)

Answer:

25 - 3x = 40            ​x=-5

1/3x - 12 = -3           x=27

Step-by-step explanation:

25-3x=40 -> subtract 25 each side .... -3x=15 -> divide -3 each side...... x= -5

Answer:

C is the answer

Step-by-step explanation:

the third one is the correct one

Answer:

No it is not greater.

Step-by-step explanation:

-2.375 is greater than -4.5.

This is because -2.375 is closer to 0 than -4.5 is. The closer the negative number is to zero, the greater it is than numbers that are far away from zero.

Step-by-step explanation:

Dimensions of the backyard is 14 m by 15 m

The length of the fence is the perimeter of the backyard.

One meter of the fence costs $6.63

Cost of the entire fence is:

Answer:

perimeter of backyard=2(15+14)=58m

it cost

1m=$6.63

58m=$6.63×58=$384.54

therefore it cost

$384.54 to put a wooden fence around Kelly's backyard.

Answer:

p=  -5

Step-by-step explanation:

because UwU and also −7+11p=3p−47

−7+11p=3p+−47

11p−7=3p−47

11p−7−3p=3p−47−3p

8p−7=−47  8p−7+7=−47+7

8p=−40      8p /8  =  −40 /8

Answer:

P= -5

Answer:

2month and 2 weeks

Step-by-step explanation:

We are told that the first plan has a $50 sign-up

fee and costs $20 per month.

let the number of months be x, and the total cost be y

y=20x+50---------1

The second plan has a $30 sign-up fee and costs $25 per

let the number of months be x, and the total cost be y

y=30x+25---------2

Equate the two equations we have

20x+50=30x+25

solve for x, collect like terms

50-25=30x-20x

25=10x

divide both sides by 10

x= 25/10

x=2.5 months

x= 2month and 2 weeks

Answer:

  31

Step-by-step explanation:

If we assume the number of potatoes is proportional to the weight, then we can write the equation ...

  n/10 = 10/3.2

  n = 100/3.2 = 31.25 . . . . . . . multiply by 10

There may be 31 potatoes in a 10-lb bag.

Answer:

(-4,-8)

Step-by-step explanation:

The solution to the system of equations is,

⇒ (- 4, - 8)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expressions are,

⇒ y = 1/2x - 6

⇒ x = - 4

Now, We can simplify the expression for y as;

⇒ y = 1/2x - 6

Put x = - 4;

⇒ y = 1/2 × - 4 - 6

⇒y = - 2 - 6

⇒ y = - 8

Thus, The solution to the system of equations is,

⇒ (- 4, - 8)

#SPJ7

Answer:

24,150

Step-by-step explanation:

Given that :

Salary earned this year = 23,000

Percentage Raise in salary for the new year = 5%

The new yearly salary can be obtained thus ;

(100% + percentage raise in salary) * salary earned this year

(100% + 5%) * 23,000

105% * 23000

1.05 * 23000

24,150

Answer:

$355

Step-by-step explanation:

85+60+35=180

5% of 3,500 is 175

175+180=355

so if i did the math right that means the answer is $355

Hopefully the right answer

Answer:

There are many solutions.

Step-by-step explanation:

A 20% discount on $50 takes us to $40.  A 25% discount on the $40 takes us to 30%.

We can also do a 4% discount to bring us to $48, followed by a 62.5% discount, to get to $30.

Given:

A figure.

To find:

The values of x and y.

Solution:

We know that, in a right angled triangle,

[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\sin 60^\circ =\dfrac{x}{16}[/tex]

[tex]\dfrac{\sqrt{3}}{2} =\dfrac{x}{16}[/tex]

Multiply both sides by 16.

[tex]\dfrac{\sqrt{3}}{2}\times 16=\dfrac{x}{16}\times 16[/tex]

[tex]8\sqrt{3}=x[/tex]

And,

[tex]\cos \theta =\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos 60^\circ =\dfrac{y}{16}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{16}[/tex]

Multiply both sides by 16.

[tex]\dfrac{16}{2}=y[/tex]

[tex]8=y[/tex]

Therefore, the missing side lengths are [tex]x=8\sqrt{3}[/tex] and [tex]y=8[/tex].
