Yanka [14]
SOLUTION:

a ) Write an equation in standard form that models your earnings.

8x + 6y = $114


b ) You worked 10 hours as a hair washer. How many hours did you work as a host?


8x + 6y = $114

8x + 6 ( 10 ) = 114

8x + 60 = 114

8x = 114 - 60

8x = 54

x = 54 / 8

x = 27 / 4 hours

x = 6.75 hours

x = 6 hours and 45 minutes

stealth61 [152]

Answer:

if 6 people take the medicine, around 5 people will get cured if the cure probability is 85%.

Step-by-step explanation:

Given that a certain medicine cures 85% of the people who take it.

As 6 people take the medicine, we need to determine how many will be cured.

As

85% = 85/100 = 0.85

All we need is to multiply 6 with 0.85.

i.e. 6 × 0.85 = 5 (Rounded to the nearest 1 or  the Ones Place)

Thus, if 6 people take the medicine, around 5 people will get cured if the cure probability is 85%.
