470 = 8.75(46 - c) + 11c
470 = 402.5 - 8.75c + 11c
67.5 = 2.25c
30 = c
If c = 30 and Soren worked 30 hours in the office, earning $11 per hour, he earns $330 from his office job. 46 - 30 = 16, which should be the remaining amount of hours Soren worked. 16 * 8.75 = 140. He earned $140 from his cashier job. $330 + $140 = $470.
The correct formula to solve this problem is A. 11c + 8.75(46 - c) = 470
Answer:
(x, y) = (3, 5/2)
Step-by-step explanation:

I'll solve by elimination here. If you invert the second equation and add it to the first, 2y and -2y would cancel out.

Now just add those from top to bottom.

Nothing else needs to be done for that part. Now, you can pick either equation and use the known value of x to solve for y.

(x, y) = (3, 5/2)
According to my calculations the 1.37 x 108 can not be past 35km because that is beyond or less than the universe we will all die sooner or later or in years or days or months so 1 2 3 4 - 5 + 2 x 5x 82 136- - 5347 + = e.140071763947832. 7 x 10
