The number of hardback books that are on the bookshelf is 29 books.

  • Let the total number of books be T.
  • Let the number of hardback books be H.
  • Let the number of paperback books be P.

<u>Given the following data:</u>

  • Total number of books = 36 books

To determine the number of hardback books that are on the bookshelf:

Translating the word problem into an algebraic expression, we have;

The total number of books is:

T = H+P

The number of hardback books is 15 more than <u>twice</u> the number of paperback books:

H =2P+15

Substituting the given parameters into the formula, we have;

36 = 2P+15+P\\\\36=3P+15\\\\3P=36-15\\\\3P=21\\\\P=\frac{21}{3}

P = 7 books

For number of hardback books:

H =2P+15\\\\H=2(7)+15\\\\H=14+15

H = 29 books

Jasper has an annual salary of $71000 and his company pays him twice a month. What is the gross income per paycheck that Jasper
Sliva [168]

Answer:

$2,958.33

Step-by-step explanation:

Jasper's annual salary is $71000.

Considering that a year has 12 months and that he gets a paycheck twice each month, the total number of paychecks (P) Jasper gets each year is:

P = 12*2 = 24

To define Jasper's gross income per paycheck (I), simply divide his annual salary by the number of paychecks in a year:

I=\frac{\$ 71,000}{24} \\I=\$ 2,958.33

Jasper's gross income per paycheck is $2,958.33.

Which of the following could be the graph of the line y = 3x - 2?
morpeh [17]

You didn't give a graph but I will visualize what it looks like for you.

The line is going through (0,-2) because that is the y-intercept.

The line has a slope of 3.

So, the line goes through:

(1,1)

(2,4)

(3,7)

(4,10)

(5,13)
