There is no diagram, so you should guess C. C is the most likely to be chosen as an answer.

Using n for the variable, write an algebraic expression that represents a number that is divisible by the given number. (Hint: A

PtichkaEL [24]

Answer:

$a) 5n\\b) 10n\\c) 3n$

Step-by-step explanation:

Let 'n' be any integer i.e. a number from the set {....., -3,-2,-1,0,1,2,3, ..... }

so 'n' can be termed as the variable here.

A number 'q' that can be divided by a a given number 'p' can be written as:

$n \times p$

When divided by 'p' :

$\dfrac{q}{p} = \dfrac{n \times p}{p}\\\Rightarrow \dfrac{q}{p} = n$

So, The number 'q' is completely divisible by 'p' leaving 'n' as the quotient.

Using this concept, let us solve the questions:

a) Using 'n' as the variable, a number that is divisible by 5 can be written as:

$5n$

b) Using 'n' as the variable, a number that is divisible by 10 can be written as:

$10n$

c) Using 'n' as the variable, a number that is divisible by 3 can be written as:

$3n$

Which simplified fraction is equal to 0.17 (7 repeating)

Varvara68 [4.7K]

So here, I would first multiply 0.17777.... (Assume that that's x) by 10, then you get

10x = 1.777777...

And then subtract x from 10x and then you get 1.6.

So that means that

10x - x = 9x

and 1.7777... - 0.17777... = 1.6

So now to solve for x, divide both sides by 9

To get 1.6/9 = x

Or 16/90 = x

Or 8/45 = x

(That explanation made no sense)

alexgriva [62]

Answer:

2x(4x + 3)

Step-by-step explanation:

8x^2 + 6

So the common terms that can be taken out are x and 2

Hence, it can be written as 2x (4x + 3)
