l = x + 5

w = x

A = x(x + 5)

[tex]A=x^{2} +5x[/tex]

Answer:

-15/2 exact form

-7.5 decimal form

-7 1/2 mixed number form

Step-by-step explanation:

Answer:

-13.5

Step-by-step explanation:

w / 6 + 5/8 = -13/8

w / 6 = -13/8 - 5/8

w / 6 = -18/8

w = -18*6/8

w = -13.5

Answer:

48

Step-by-step explanation:

Given ratio of males to females at a party is 3 : 5.

Let the numbers of males and females be 3x and 5x respectively.

According to the given description:

No of females = No of males + 13

Therefore,

5x = 3x + 12

5x - 3x = 12

2x = 12

x = 12/2

x = 6

No of people at the party

= 3x + 5x

= 8x

= 8*6

= 48

Answer:

x

Find the prime factors of each term in order to find the greatest common factor (GCF).

Answer:

32x +20

Step-by-step explanation:

Answer:

32x+20

Step-by-step explanation:

If you use distributive property you would multiply each number by 4. 4 times 8x is 32x and 4 times 5 is 20, and when you put those together you get 32x+20!

Why did you7 ask a question then anwser it yourself

Step-by-step explanation:

Answer: 8 and 2

Step-by-step explanation:

this is simple, since we only have 10 numbers to work with. i just kept experimenting with numbers until i got one that had a difference of 6. no strategy, just brain power. hope this helps! xoxo

Answer:

So negatove numbers are gonna be impossible becuase we know that the highest we can go is -10+20=10 but it’ll give a whole different difference when subtracted.

And it can’t be greater then 10 becuase if you do add them it won’t be 10

SO it has to be between 1-10

So what equals 10?

5/5

2/8

8/2

6/4

4/6

3/7

7/3

Now 5 and 5 is out cause if subtracted its 0

2/8  and 8/2 works, if added you get 10 but when subtracked the way for 8/2 from left to write it’ll give 6 which is the only one which will give.

final answer the two numbers are 8 and 2

Answer:A

Step-by-step explanation:

Answer:

The solution of the equation    y = 36

Step-by-step explanation:

Explanation:-

Given equation -3x-y =-51

Given that x =15 in equation -3x-y=-51

                 ⇒        - 3(15) - y = -51

                ⇒         - 15 - y =-51

                 ⇒         -15+ 51 = y

               ⇒            y = 36

Answer: The other point is (17, -6).

Step-by-step explanation:

Midpoint (x,y) of the line segment joining (a,b) and (c,d) is given by :-

[tex](x,y) =(\dfrac{a+c}{2}, \dfrac{b+d}{2})[/tex]

Here, we need to find the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1).

Let other point be (a,b), then

[tex](7,1)=(\dfrac{-3+a}{2},\dfrac{8+b}{2})\\\\\Rightarrow\ \dfrac{-3+a}{2}=7\ \text{ and }\dfrac{8+b}{2}=1\\\\\Rightarrow\ -3+a = 7\times2 \text{ and } 8+b=1\times2\\\\\Rightarrow\ -3+a=14\text{ and }8+b=2\\\\\Rightarrow\ a=14+3, \ \ \ b= 2-8\\\\\Rightarrow\ a=17, b= -6[/tex]

hence, the other point is (17, -6).

Answer:

-4

Step-by-step explanation:

because the line is going from top to bottom it is negative

you take the rise ( the Y value) / the run (the X Value)

the Y and X value can be pulled from any two points

Answer:y=2x

Answer:

the cost each of one package of tulip bulbs and one bag of daffodil bulbs is $14 and $19 respectively

Step-by-step explanation:

The computation of the cost of each of one tulip package bulbs and one bag of daffodil bulbs is shown below:

Let us assume the tulip bulbs be x

And, the daffodil bulbs be y

According to the question

7x + 9y = $269.........(1)

7x + 2y = $136..........(2)

Now subtract equation 2 from equation 1

7y = $133

y = $19

Now put the value of y in any of the above equation

7x + 9($19) = $269

7x = $269 - $171

x = $14

Hence, the cost each of one package of tulip bulbs and one bag of daffodil bulbs is $14 and $19 respectively

Answer:

21

Step-by-step explanation:

the greatest possible length that the two ribbons would be when the ribbons are divided by their lowest common multiple.

The lowest common multiple of 63 is 3. 63/3 = 21

The lowest common multiple of 42 is 2 = 42/2 = 21

Answer:

1/6+1/3

=3+6/6×3

=9/18

=1/2

Step-by-step explanation:

Hope you find this helpful!

Answer: It does because 1/3 is equal to 2/6. in order to add them, they have to have the same denominator. and if you add 2/6 to 1/6, you get 3/6. 3/6 is also equal to 1/2, if you divide both sides by 3.

Step-by-step explanation:

Answer:

c = 17

Step-by-step explanation:

Answer:

i THINK it is 15. im so so so super sorry if im wrong-have a nice day!

Step-by-step explanation:

Answer:

I think its the third one but i might be wrong

Step-by-step explanation:

Step-by-step explanation:

sin2x - sinx = 0

2sinxcosx - sinx = 0

(Double Angle Formula)

sinx(2cosx - 1) = 0

Either sinx = 0 or cosx = 1/2.

When sinx = 0,

x = 0 or x = π.

When cosx = 1/2,

x = π/3 or x = 5π/3.

Hence the solutions are

x = 0, x = π/3, x = π or x = 5π/3.

Answer:

780

Step-by-step explanation:

So 5% is 39 so 5% x 20 is 100% do the same with the 39 so do

39 x 20 = 780
