The tables show the amount earned by James and Paco working at the same store.


What two equations can represent James and Paco's hourly wages, where h is the number of hours worked and d is the amount of money earned?

Compare the equations to determine if there is any difference between what James and Paco make each hour.

Answers

Answer:

Step-by-step explanation:

In order to determine if James and Paco earn different amounts of money per hour, you must find how much money they make in one hour.

James:

James makes $35.40 in 3 hours. So, in 1 hour, he would make 35.40/3 = 11.8.

James makes $11.80 an hour.

Therefore, his equation would be d = 11.8h

Paco:

Paco makes $24.00 in 2 hours. So, in 1 hour, he would make 24/2 = 12.

Paco makes $12.00 an hour.

Therefore, his equation would be d = 12h

Hence, Paco and James make different amounts of money. Paco makes 20 cents, or $0.20, more than James.

Answer:

d(James) = 11.8h

d(Paco) = 12h

Paco makes $0.20/h more than James

Step-by-step explanation:

equation: y = ax + b

James:

d(Amount of money earned) = ah(number of hours worked) + b

If James worked 3 hours: 3a + b = 35.4

If James worked 5 hours: 5a + b = 59

If

3a + b = 35.4

b = 35.4 - 3a

Then

5a + b = 59

5a + 35.4 - 3a = 59

2a = 59 - 35.4

2a = 23.6

a = 23.6/2

a = 11.8

If a = 11.8, then

3a + b = 35.4

3(11.8) + b = 35.4

35.4 + b = 35.4

b = 0

If a = 11.8 and b = 0

d(Amount of money earned) = ah(number of hours worked) + b

d = 11.8h

Each hour James works, he makes $11.8

Paco:

d(Amount of money earned) = ah(number of hours worked) + b

If Paco worked 2 hours: 2a + b = 24

If Paco worked 4 hours: 4a + b = 48

If

2a + b = 24

b = 24 - 2a

Then

4a + b = 48

4a + 24 - 2a = 48

2a = 48 - 24

2a = 24

a = 24/2

a = 12

If a = 12, then

2a + b = 24

2(12) + b = 24

24 + b = 24

b = 24 - 24

b = 0

If a = 12 and b = 0

d(Amount of money earned) = ah(number of hours worked) + b

d = 12h

Each hour Paco works, he makes $12

Drag and drop the value of 5t in the box. 5t=

Answers

Answer:

The value of 5t will be 15.55

Step-by-step explanation:

Given equation is;

9t = 27.99

As it is stated that the relationship is constant, therefore, we will find the value of t by dividing 27.99 by 9

Now, we will put t=3.11 to find 5t.

The value of 5t will be 15.55

the value is 15.55

-3x + 1 < 7 on number line

Answers

Answer:

D.    x is greater than -2

Step-by-step explanation:

Ok so,

-3x + 1 < 7

First, do the opposite of +1 which is -1 so you have to subtract 1 from both sides. Which should look like this.

-3x < 6

Then you divide -3 with 6 which will give you -2. You change the inequality sign becuase you divided with a - number.

You call your teacher and find out that the second part of the note should have said “sell four hot dogs and two bags of chips for $10.” What does that do for your system of equations now? With this new information, how much should each item cost? Again, show all of your work.

Answers

Answer:

h = $4 a hotdog

c = $2 bag of chips

Step-by-step explanation:

3h + c = 14

2h + c = 10

3h + c = 14

-2h - c = -10

h = $4 a hotdog

2(4) + c = 10

8 + c = 10

c = $2 bag of chips

Answer:

h = $4 a hotdog

c = $2 bag of chips

Step-by-step explanation

3h + c = 14

2h + c = 10

3h + c = 14

-2h - c = -10

h = $4 a hotdog

2(4) + c = 10

8 + c = 10

c = $2 bag of chips
