Question

write five linear equations from one variables from real life situations​

Answer 1

Answer:

1. When the age of father is 5 yrs. more than 4 times his son's age.

Let the ages of father be x yrs. and son be y yrs. respectively.

• x = 4y + 5

2. When the speed of train is twice that of car.

Let the speed of train be x km/h and that of car be y km/h respectively.

• x = 2y

3. When Amount of cholesterol level decreases half of the cholesterol gained.

Let the decreased cholesterol level be x and gained cholesterol be y respectively.

• x = y/2

4. When speed of ball freely falling is half of the speed at which it was thrown upward.

Let the speed of the ball freely falling be x m/s and that of thrown be y m/s respectively.

• x = y/2

5. When weight lost is two third of the weight gained.

Let the lost weight be x kg and gained weight be y kg respectively.

• x = 2y/3

Answer 2

Answer:

linear equation use one or more variable where one variable is depended on the other almost any situation where there is an unknown quantity can be represented by a linear equation like figuring about income over time, calculating mileage rates for pendings profit many people use linear equation every day even if they do the calculation in their head without drawing a linear graph..
