2(3)+3(3)=15
6+9=15
15=15
M=3

One can write down all possilities:
- m =0 , n= 5
- m cannot take value 1 or 2.
- m= 3, n= 3
- m cannot take value 4 or 5
- m= 6 , n= 1
So the sum 0 + 3+ 6 = 9

Try this explanation:

Note, in the 1st row given '9x', in the 2d one - '9(0)', then it means the substitution '0' instead of 'x'. In other words x=0 !

answer: x-intercept is '0', y-intercept is '12'

The sum of Joy's age and her brother's age is 24. Joy's brother's age is 3 years older than twice joy's age. What is the differe

enyata [817]

Let Joy be x years old

Joy's brother's age is 3 years older than twice joy's age.
Joy's Brother = 2x + 3

The sum of Joy's age and her brother's age is 24.
x + 2x + 3 = 24
3x + 3 = 24
3x = 24 - 3
3x = 21
x = 21 ÷ 3
x = 7

Joy:
x = 7

Brother:
2x + 3 = 2(7) + 3 = 17

Difference in their age = 17 - 7 = 10 years

They are 10 years apart.
