Joey earns $12 an hour. blake earns $16 per hour. joey receives a raise of $1.50 every six months, and blake receives a raise of $0.50 every six months..

which equation can be used to find x, the number of six month intervals it will take joey to earn hourly the same as blake?
a) 12x + 1.5x = 16x + 0.50x
b) 12x + 1.5x = 16 + 0.50
c) 12 + 1.5x = 16 + 0.50x
d) 12x + 1.5 = 16x + 0.50

 C (12 + 1.5x = 16 + 0.50x)

Explanation:

This is correct because when setting up this sentence as an equation, you need to look at the numbers and how they're used. There are independents and dependents.

independent:

12,16

dependent:

1.50,0.50

Furthermore, there are 1 of each on both sides of the equation, match them from the equation by name and you get the answer.

∞ this is your sign

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
