Answer:
100
Step-by-step explanation:
Write in an equation:
4=4%x, then divide 4% from both sides, and then you get 100.
The standard form would be y = 7x^2 - 42x + 67
Step-by-step explanation:
l dont understand your question
is it 3 and a fifth or 31/5
x + 2y = 4
2x - 2y = 5
Adding both the equations:
x + 2y + 2x - 2y = 9
3x = 9
x = 3
y = 4-x /2 = 1/2
