When you divide the top and bottom you get a decimal number. So you compare those. Or if you draw it out then you can see that 21/30 is bigger.
Answer:
= 0.8 + -0.4y
Step-by-step explanation:
Simplifying
5x + 2y = 4
Solving
5x + 2y = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
5x + 2y + -2y = 4 + -2y
Combine like terms: 2y + -2y = 0
5x + 0 = 4 + -2y
5x = 4 + -2y
Divide each side by '5'.
x = 0.8 + -0.4y
Assuming that no overtime was factored into his wages, Alex would have gotten a gross pay of $359.60. This was done by multiplying $7.86 x 45.75 hours.
Assuming that overtime was factored into his wages, Alex would have gotten a gross pay of $382.19. This was done by figuring out how much "time and a half" is for over time. "time" = 7.86; "and a half"= 7.86/2= 3.93
Time AND a half would equal 7.86 + 3.93= 11.79.
So, Alex would get an additional $11.79 for the hours OVER 40 hours which was 5 hours and 75 minutes..
11.79 x 5.75 = 67.79
Total hours for a 40 hour work week for Alex with 7.86 would equal a gross pay of 314.40. Plus 67.79. = 382.19
You have to look at the equation and find a common factor bettween all parts. SO, we see they all have an x, so that is the first thing you can factor out. They also have
2x(5x2 4x -3) C
Answer:
Step-by-step explanation:
