I don't know 5 and 7 it's to complicated for me plus I haven't learned how do those kind
6)7/3 (c+3)=1/3-c
7/3c+7=1/3-c
3×7/3c+3×7=3×1/3-3c
7c+3c=1-21
10c=-20
c=-2
Answer:
The expression giving her net earnings for a day with more than 8 hours worked is X = 80 + 15H, where H means "extra hours worked".
Step-by-step explanation:
Given that Daisy works at an ice-cream parlor earning $10 per hour for the first 8 hours she works in a day, and 1.5 times her hourly wage for every extra hour she works, in order to know how much can she make in a day working more than 8 hours the following equation has to be made:
X = (8 x 10) + (H x (1.5 x 10))
X = 80 + 15H
Therefore, if Daisy works 13 hours, the equation works as follows:
X = 80 + 15x13
X = 80 + 195
X = 275
