Question

please answer the following i will mark as brainlist drs​

Answer 1

Step-by-step explanation:

1) Given numerator is 1 less than the denominator

Fraction = x --1

x

2) Cost of book(x) exceeds twice the cost of pen(y)

→ Cost of book = 2 × Cost of pen

→ x = 2y

→ x -2y = 0

by Rs. 10

→ x -2y = 10

x -2y -10 = 0

3)Linear Equations in Two Variables. If x represents the present age of father and y represents the present age of the son, then the statement “present age of father is 5 more than 6 times the age of son” in terms of mathematical equation is: 6x + y = 5.

4)The cost of getting 2 toy telephones packed, if cost of 1 ball is  5 and there is a fixed cost of 2.for packing a toy telephone is Rs.44

Step-by-step explanation:

Let the cost of 1 ball be x

Cost of 4 balls = 4x

Let the cost of 1 toy telephone be y

We are given that The cost of a toy telephone is the same as cost of 4 balls.

---1

So,

Now find the cost of getting 2 toy telephones packed, if cost of 1 ball is  5 and there is a fixed cost of 2.

Cost of 1 ball = 5

Cost of 4 balls = 4x = 4(5) = 20

So, By -- 1

Cost of 1 toy telephone = 20

there is a fixed cost of 2.for packing a toy telephone

So, Total cost of 1 toy telephone = 20+2=22

So,Total cost of 2 toy telephone = 22+22=44

Hence the cost of getting 2 toy telephones packed, if cost of 1 ball is  5 and there is a fixed cost of 2.for packing a toy telephone is Rs.44

Answer 2

Answer:

Below are the linear equations of two variables of the given questions :-

$(i) \: x = y - 1$

$(ii) \: x - 2y - 10 = 0$

$(iii) \: x - 6y = 5$

$(iv) \: y = 4x$

Hope it helped you....
