4 less than n is 9.?

Answers

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:

x = 5

Step-by-step explanation:

x/8 + x/10 = 9/8

=> 10x/80 + 8x/80 = 9/8

=> 18x/80 = 9/8

=> 18x = 9/8 (80)

=> 18x = 90

=> x = 90/18

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

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