Answer:
The system would be:
4x + 2y = 140
2x + 3y = 150
Step-by-step explanation:
If we represent the cost of sweats by the letter x and the jeans by the letter y, we can then write an equation for each of the situations using the number of each in each situation.
4x + 2y = 140
2x + 3y = 150
The correct answer is B. Reflection across the line y = -x followed by a rotation 180° counterclockwise about the origin.
56 divided by 40 is 1.4. Multiply that by 100 and you get 140.
This is the long way of doing it, but it's the way I've always done it.
