Ruby buys 24 books and 5 pens.she pays with a 500 rupee note and get rs90 as change.shania bought 12 books and 10 pens for rs280

just olya [345]

The cost of one pen is Rs 15.

<h3>How to find the cost of one pen?</h3>

It is given that Ruby paid with a 500 rupee note and got Rs 90 back.

This means that she spent 410 rupees.

Therefore the cost of 24 books and 5 pens is Rs 410.

Let the cost of books be x and the cost of pens be y.

Therefore, we can form the following equations:

24x + 5y = 410 (1)

12x + 10y = 280 (2)

We have to find the value of y.

Multiply the second equation by 2:

24x + 20y = 560 (3)

Now subtract the first equation from the third equation:

24x + 20y - 24x - 5y = 560 - 410

15y = 150

y = 15.

The variable y represents the cost of one pen.

This means that the cost of one pen is Rs 15.

Therefore, we have found that the cost of one pen is Rs 15.

Could someone please help me on this? This is one question

Aleks [24]

The point-slope formula:

$y-y_1=m(x-x_1)$

We have a slope m = 2 and point (-8, 2)

Substitute:

$y-2=2(x-(-8))\\\\y-2=2(x+8)$

This table shows the relationship of the total number of pieces of fruit to the number of bananas.

ddd [48]

Given:

The table that shows the relationship of the total number of pieces of fruit to the number of bananas.

To find:

Why is $\dfrac{6}{5}$ not equivalent to $\dfrac{3}{2}$ .

Solution:

If a, b, c are real numbers, then

$\dfrac{a}{b}=\dfrac{a\times c}{b\times c}$

The given fraction is $\dfrac{3}{2}$ . It can be written as:

$\dfrac{3\times 2}{2\times 2}=\dfrac{6}{4}$

The number 3 is multiplied by 2 to get 6. So, the 2 should also be multiplied by 2. The ratio should be $\dfrac{6}{4}$ , not $\dfrac{6}{5}$ .

Therefore, the correct option is A.

What is the solution of 1/x+1/3lessthan1/5

timama [110]

Answer:

X > - 7.5

Step-by-step explanation:

1/X + 1/3 < 1/5

1/X + 1/3 < 1/5

Step one:collect like terms

1/X < 1/5 -1/3

Step two: Find the L.C.M of the R.H.S which is 15

1/X < 3-5/15

1/X < -2/15

1/X < -2/15

Step three: Take the reciprocal of both sides.

X < 15/-2

Dividing through by -2 changes the inequality sign, Hence

X > -7.5
