2x -3y = 12;
x + 3y = 6;
__________(+)
3x = 18;
x = 18÷3;
x = 6;
Then, 3y = 6 - 6;
3y = 0;
y = 0÷3;
y = 0;
So all you need to do is 7.35kg takeaway 2.6kg = 4.75kg
Mrs Warburton's bag now weighs 4.75kg
The correct answer is A -1.5
I think 30 because I did all the equation and I got 30
Answer:
For company A, y = 24x + 42
For company B, y = 28x + 25
Step-by-step explanation:
x is the number of containers
y is the total cost
For company A, y = 24x + 42
For company B, y = 28x + 25
For the cost of both companies to be the same, then
24x + 42 = 28x + 25
28x - 24x = 42 - 25
4x = 17
x = 4.25
Mr Lycan would have to order about 4 containers so the cost would be the same from each company
