Answers

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.

There are 21 apples,28 pears and 49 oranges. These are to be arranged in heaps containing the same number of fruits. Find the greatest number of fruits possible to keep in each heap. How many heaps are formed by this arrangement?​

Answers

21+28+49= 98 (fruit)
98/49=2

2 heaps can be formed.
Each would have 49 fruit.

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

The mean of 6 numbers is 17. Four of the numbers are -15, 17, 20 and 22. The remaining two numbers are each equal to x. Calculate (i) the sum of the 6 numbers, (ii) the value of x.​

Answers

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

I need the steps and answers please

Answers

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

Compare using <, >, or =.
