500.

Solution:  210 is 42% of X  

Equation: Y = P% * X  

Solving our equation for X

X = Y/P%

X = 210/42%  

Converting percent to decimal:

p = 42%/100 = 0.42  

X = 210/0.42  

X = 500

Oh my goodness please help its confusing.

Probably the easiest way to do these is to convert them to slope intercept form by solving for y.  When we have y=mx+b, we read off the slope m.

-5x + 2y = 10

Add 5x to both sides,

2y = 5x + 10

Divide both sides by 2,

y = (5/2) x + (10/2)

Obviously 10/2=5 but we don't care about that for this problem.  We read off the slope as

Answer: 5/2, last choice


12 = 4x - 6y

Adding 6y and subtracting 12,

6y = 4x - 12

Dividing by 6,

y = (4/6) x - (12/6)

y = (2/3) x - 2

Answer: 2/3
