Y - 2 / 4
I don't really know how to explain it, but y - 2 / 4 is equivalent to 1/4y - 1/2
Every hour is 15$, thus you can do x for hours, and the function would be 15x
Answer:
x : -3
Step-by-step explanation:
1) 15x-3(3x + 4) = 6 (distribute -3 to the numbers on the inside of parentheses)
2) 15x - 9x - 12 =6 (combine like terms 15x-9x = 6x)
3) -6x - 12 = 6 (add twelve to both sides, add the 12 to cancel out the 12)
4) -6x = 18 (divide the -6 on both sides)
5) x = -3
From the given scenario in this item, we can say that the sum of x and y is 500. By the aluminum balance, the equation that we can formulate from this,
0.25x + 0.40y = (500)(0.35)
The system of linear equations that can best express the given is,
x + y = 500
0.25x + 0.40y = 175
