There are 162 magazines and books in a library. There are 54 more books

Strike441 [17]

Answer:

108 books.

Step-by-step explanation:

Let the number of magazines = m

Let the number of books = b

Given the following data;

Total number of m & b = 162

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

$b = m + 54$ ......equation 1

$m + b = 162$ ......equation 2

Substituting equation "1" into equation "2" we have;

$m + m + 54 = 162$

$2m + 54 = 162$

$2m = 162 - 54$

$2m = 108$

$m = \frac {108}{2}$

m = 54

Now to find the number of books;

$b = m + 54$

Substituting the value of "m" into the equation, we have;

$b = 54 + 54$

b = 108

Therefore, the total number of books in the library is 108 books.

Julio is playing a trivia game. On his first turn, he lost 95 points. On his second turn, he lost 55 points. On his third turn,

erastovalidia [21]

Answer:

Julio's score change by (-230) or we can say Julio lost 230 points after his first three turns.

Step-by-step explanation:

We are given the following in the question:

Points lost after first turn = 95

Points lost after second turn = 55

Points lost after third turn = 80

We have to evaluate the change in Julio's score after his first three turns.

This could be done by adding three negative integers.

Here we use negative integers to represent Julio's point as these points were lost in the turn.

Change in Julio's score =

$=1^{st}\text{ turn} +2^{nd}\text{ turn} +3^{rd}\text{ turn} \\=(-95) + (-55) + (-80) \\=-230$

Thus, Julio's score change by (-230) or we can say Julio lost 230 points after his first three turns.

Write an equivalent expression for each question

Mandarinka [93]

Answer:

A. 16 - 4 x = 4(4 - x)

B. 4 x + 8 = 4( x + 2)

C. -8 b - 24 = -8(b + 3)

D. 54 + 9 x = 9 (x + 6)

Step-by-step explanation:

Here, the given expressions are:

A. 16 - 4 x

Now, 16 and 4 have 4 as their COMMON FACTOR.

⇒Taking out 4 as the factor, we get: 16 - 4 x = 4 ( 4 - x)

Hence, the equivalent expression of 16 - 4 x = 4 ( 4 - x)

B. 4x + 8

Now, 4 and 8 have 4 as their COMMON FACTOR.

⇒Taking out 4 as the factor, we get: 4 x + 8 = 4 ( x + 2)

Hence, the equivalent expression of 4 x + 8 = 4 ( x + 2)

C. -8b - 24

Now, -8 and -24 have (-8) as their COMMON FACTOR.

⇒Taking out (-8) as the factor, we get: -8b - 24 = (-8) ( b+ 3)

Hence, the equivalent expression of -8b - 24 = (-8) ( b+ 3)

D. 54 + 9x

Now, 54 and 9 have (9) as their COMMON FACTOR.

⇒Taking out (9) as the factor, we get: 54 + 9 x = 9( 6 + x)

Hence, the equivalent expression of 54 + 9 x = 9( 6 + x)
