Question 18
The answer is 4 days.
Because,
Kevin =3×n
Anita =4+ (2×n)
Equating the two equations.
3n=4+2n
3n-2n=4
n=4
Question 19
When the solution is (4,1), it means the value of y=1 and x=4.
The answer is;
y=x-3
y=-3x+13. Since when the values of x and y are substituted they satisfy the system.
Question 20
The system has no solution.
This is because the line are parallel and they do not intersect to give a solution.
3:2:1
r:b:9
To get to 9 from 1, you are multiplying by 9.
Therefore, multiply each number by 9.
27:18:9
So, 27 red and 18 blue.
Hope this helps!!
