Question

In a class no. of girls is x and that of boys is y. Also, the no. of girls is 10 more than the no. of boys. Write the given data in the form of a linear equation in two variables. Also, represent it graphically. Find graphically the no. of girls, if the no. of boys is 20. valid answers with graph will be marked brainliest........​

Answer 1

Step-by-step explanation:

Equation is

x=y+10

boys are 20.

y=20.

girls is x=y+ 10.

x= 20+10 = 30

Answer 2

Answer:

Step-by-step explanation:

According to question,

In a class no. of girls is x and that of boys is y.

# The no. of girls is 10 more than the no. of boys

x = 10 + y  

Graph for x = 10 + y

x = 10 + y

                   x      0        5     10

                   y    -10      -5     0

Plotting the values of x and  y in the graph we get....

see  the figure

Now

According to question,

Find graphically the no. of girls, if the no. of boys is 20.

 x = 10 + y

 x = 10 + 20

x =  30

Hence solved!!!
