3.5x + 6.5y = 1800
Move 3.5x to another side.
6.5y = -3.5x +1800
Divide by 6.5.
y = -3.5/6.5x + 1800
If we round it would be:
Y = 0.5x + 1800
0.5x is the slope and 1800 is the y-intercept.
Hope that helps.
Answer:
5/(3x+2) = 7/(5x-2)
<=>5*(5x-2) = 7*(3x+2) (x is not equal to -3/2 or 2/5)
<=> 25x -10 = 21x +14 (x is not equal to -3/2 or 2/5)
<=> 4x = 24 (x is not equal to -3/2 or 2/5)
<=> x = 6 (valid)

Answer:
The number is 3
Step-by-step explanation:
Hi,
4 ( 3 + 5x) = 72
