Two numbers are n and 2(n+3). a The sum of the numbers is 90.
Write down an equation to show this.
b Solve the equation.
c Find the two numbers.

Step-by-step explanation:

N +2(n+3)=90

N+2n+6=90

3n=84

N=28 (1st number)

2(n+3)=2(28+3)=2*31=62 (2nd number)

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

c
