Gia got some books from Library yesterday she got five books today Gia returned three books Gia has six books how many books did

makvit [3.9K]

Answer: 4

Explanation:

You can write an algebraic expression to represent the sequence with the books in this way:

yesterday she got five books: 5
today returned three books: - 3
how many books did Gia have to begin: n
At the end she has six books, which means that you can set an equality:

n + 5 - 3 = 6

Now you follow these steps to clear the unknown:

do the operations in the left side: n + 2 = 6
use subtraction property of equality: n = 6 - 2
do the operations: n = 4

And that is the number of books whith which Gina started: 4

The sum of the three consecutive integers is -27. What is the product of the smallest and largest of the three integers?

Aleksandr [31]

Answer:

B. 80

Step-by-step explanation:

3 consecutive integers: x-1 , x , x+1

(x-1) + x + (x+1) = -27

3x = -27

x = -9

smallest: -9-1 : -10

largest: -9+1 : -8

product of the smallest and largest of the three integers: (-10)*(-8)=80

Mr. Lawrence used 100 tiles when he put a new floor in the kitchen 34 tiles are squares and 16 tiles are rectangles write the to

Oliga [24]

<h3>Fraction of square tiles = $(\frac{4}{25}) = 0.16$ </h3><h3>Fraction of rectangle tiles = $(\frac{17}{50}) = 0.34$ </h3>

Step-by-step explanation:

Total number of tiles to be used in the kitchen = 100

The total number of square tiles = 34

The total number of rectangle tiles = 16

Now, calculating the total fraction of square tiles:

The fraction of square tiles = $\frac{\textrm{Total number of square tiles}}{\textrm{Total number of tiles}} = \frac{16}{100} = \frac{4}{25}$

Also, solving the fraction, we get $\frac{4}{25} = 0.16$

So, the decimal value of square tiles = 0.6

Calculating the total fraction of rectangle tiles:

The fraction of rectangle tiles = $\frac{\textrm{Total number of rectangle tiles}}{\textrm{Total number of tiles}} = \frac{34}{100} = \frac{17}{50}$

Also, solving the fraction, we get $\frac{17}{50} = 0.34$

So, the decimal value of rectangle tiles = 0.34
