Mathematics
1 answer:
Paraphin [41]3 years ago
8 0

Answer:

I will provide the steps below.

Step-by-step explanation:

First, You will need to plug in the 8.

2(8)-(1/-3)=-5  

Multiply

16-(-1/3)=-5

If we have two negitive it turns into possitive.

16+1/3=-5

16+1/3=-5

This statement is not true becuase if y=8 the equation will be (16+1/3)=5

*Make sure your giving me the right eqution otherwise this statment is false.*

8. Colby and Cheryl work in different local supermarkets. Colby regularly earns $8.90 per hour,
faust18 [17]

Answer:

colby

hourly rate =$8.90

overtime rate = time and a half = 1.5

the hourly overtime rate is the product of the overtime rate and the hourly rate.

hourly overtime rate= overtime rate × hourly rate

= 1.5 × $8.90

= $13.35

Cheryl

hourly rate = $7.10

overtime rate = double time = 2

the hourly overtime rate is the product of overtime rate and the hourly rate.

hourly overtime rate = overtime rate × hourly rate

= 2 × $7.10

= $14.20

<h3>Comparison</h3>

we note that the hourly overtime rate of cheryl is higher than the hourly overtime rate of colby, which implies that cheryl earns more for one hour of overtime.

we are also interested in the difference of the hourly overtime rate:

hourly overtime rate colby — hourly overtime rate cheryl

= $14.20 – $13.35

= $0.85

thus cheryl earns $0.85 more for one hour of overtime than colby .

<h3>result</h3>

<h2>cheryl,$0.85</h2>
