Answer:
y = 3.3x + 20
Step-by-step explanation:
-2/3x +1/5y = 4 y = mx + b
-2/3x + 1/5y = 4
-2/3 -2/3
1/5y = 2/3 + 4
1/5 / 2/3 = 3.3
1/5 / 4 = 20
y = 3.3x + 20
Answer:
Mike's average monthly salary is $ 1,814.
Step-by-step explanation:
To determine Mike's average monthly salary, taking into account that he earns $ 284, $ 292, $ 418, $ 350, and $ 470 weekly, these amounts must be added for the 5-week duration of the month through the following calculation:
