Nina is 10 years younger than deepak. deepak is 3 times as old as nina. which system of equations can be used to find d, deepaks age and n, nina’s age

We can use linear system of equation with one variable.

Step-by-step explanation:

It is given that,Nina is 10 years younger than Deepak.

Deepak is 3 times as old as Nina.

To solve this using linear equation

Let d be the age of Deepak and n be the age of NIna

we can write,

n = (d - 10)   ---(1)

d = 3n    

d = 3(d - 10)  (2)

d = 3d - 30

3d - d = 30

2d = 30

d = 30/2 = 15

n - d - 10 = 15 - 10 = 5

Therefore the age of Deepak = 15 and age of Nina = 5

there is no

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
