What is 42/77 in simplest form?
4/7
6/11
7/11
6/7

Answer:

D

Step-by-step explanation:

When you add up

[tex](4m^3+2m^2-m)+(4m^2+2m^2-2m)+(7m^3-3m^2+2m)[/tex],

you have [tex]15m^3+m^2-m[/tex],

which is what D is.

Side note:

You only add up the exponents when you multiply.

[tex]4 {m}^{3 } \: + 2 {m }^{2} \: - \: m \: [/tex]

[tex]7 {m}^{3} \: - 3 {m}^{2} + \: 2m[/tex]

[tex]4 {m}^{3} \: + 2 \: {m}^{2} \: - 2m[/tex]

[tex] = (4 {m}^{3} + 2 {m}^{2} - m) + (7 {m}^{3} - 3 {m}^{2} 2m) + (4 {m}^{3} + 2 {m}^{2} - 2m)[/tex]

[tex] = 4 {m}^{3} + 7 {m}^{3} + 4 {m}^{3} + 2 {m}^{2} - 3 {m}^{2} + 2 {m}^{2} - m + 2m -2m [/tex]

Answer:

13. Bestie literally 9+4

Answer:When solving a question like "What number is 4 less than 9?", take a close look at what it is really asking.

You have the number 9 and you are looking for a number that is 4 less than 9. In other words, if you have 9 and take away 4, then how many do you have?

You guessed it! This is a subtraction problem. 9 is the minuend and 4 is subtrahend and the answer we are looking for is the difference.

Therefore, to solve "What number is 4 less than 9?", you subtract 4 from 9 like so:

9 - 4 = 5

Answer:

1/2 x 1/8 = 1/16 in fraction form.

Answer:

x = -4

Step-by-step explanation:

10 + 10 = 20 / -5 = -4

Answer:

-5x-10=10

add 10 to both sides (why? to cancel out the -10 on the left side and make it 0 since 10+-10 = 0)

-5x=20

divide both sides by -5. to isolate x.

x=-4

Step-by-step explanation:

Hi Friend !!!

Here is ur answer !!!

(x-1)(x+1)(x²+1)(x^4 + 1)

= (x²-1)(x²+1)(x^4 + 1)

=( x^4 -1)(x^4 + 1)

=( x^8 -1)

The whole is with the help of (a-b) (a+b) = a²-b²

Hope it helps u :-)

Answer:

you could use 3,5,1 as your answer, but I have a feeling you are expected to answer x = 15 / (1 - 2y)  It depends on what you have been told.

Step-by-step explanation:

Take out x as a common factor.

I suspect there are many possible answers -- well more than 1 unique answer.

x (1 - 2y) = 15             Divide by 1 - 2y

x = 15 / (1 - 2y)

1 - 2y =  3

-2y =  2

y = -1

What does that give you?

1 - 2(-1) = 3

x = 15/3

x = 5

1- 2y = 5

- 2y = 4

y = -2

x = 15 / 5

x = 3

1 - 2y = 15

-2y = 15 - 1

-2y = 15

y = - 7

x = 15 / 15 = 1

Answer:

greatest no. of fruits possible to keep in each heap is 7

no. of heaps is 14

Step-by-step explanation:

21 apples

28 pears

49 oranges.

[tex]28 \div 21[/tex]quotient will be 1 and 7 remainder

[tex]21 \div 7[/tex]

quotient will be 3 and 0 remainder

[tex]49 \div 7[/tex]

quotient will be 7 and 0 remainder

hence, the greatest number of fruits is 7

Now,no. of heaps formed to keep fruits

Apple = 21

Pear = 28

Orange =49

Now, 21+28+49 = 98

Then, one heap can store can 7 fruits

Then,let the no. of heaps be x

x= 98÷7

x=14

Hence, no. of heaps = 14

Answer:

es 21

Answer:

x = 3+11

y = 4 - 6

P(x,y) = P(15,-2)

Answer:

Step-by-step explanation:

x - Coordinate  = 11 units to the right of 3 =  3 + 11 = 14

y -Coordinate  = 6 units above 4 = 4 + 6 = 10

P(14 , 10)

Answer:

Value of X is 18

Step-by-step explanation:

x/3 - x/6 = 2

multiply first fraction by 3 so u get X by its self then multiply the 2 by 3

x - x/6 = 6

then multiply the fraction by 6 to get X by itself then multiply the 6 by 6 because what u do to one side u have to do to the other

2x/2 = 36/2

x= 18

Answer:

C. [tex] 2 {x}^{3} + 5 {x}^{2} - 8x - 4[/tex]

Step-by-step explanation:

[tex] - (2x - 3) + (2 {x}^{3} + 5 {x}^{2} - 6x - 7)[/tex]

[tex] - 2x + 3 + 2 {x}^{3} + 5 {x}^{2} - 6x - 7[/tex]

[tex] - 8x - 4 + 2 {x}^{3} + 5 {x}^{2} [/tex]

[tex] = 2 {x}^{3} + 5 {x}^{2} - 8x - 4[/tex]

Answer:

I)102

ii) 29

Step-by-step explanation:

mean:17

N= 6

-15,17,20,22,x,x

Mean=Ex/N

or,17= -15+17+20+22+X+X /6

or, 17= 44+2x / 6

or, 17*6= 44+2x

or, 102-44= 2x

or , 58= 2x

or, X= 58/2

(X= 29)

now,

X=29

-15+17+20+22+29+29=102
