Erica tiene 85 libros y 9 estanterias, para colocar todos los libros sin que le sobre ninguno, puede colocar 17 libros en 5 estanterias.

Primero sabemos que Erica tiene, al menos, 50 libros, entonces si definimos L como el numero de libros que tiene, tendremos:

L ≥ 50.

Si coloca 11 en cada estanteria, le sobran 8, entonces podemos escribir:

L = n*11 + 8   (donde n es un número entero).

Si coloca 9, le sobran 4, entonces:

L = k*9 + 4 (donde k es un número entero).

Entonces tenemos que:

n*11 + 8 =  k*9 + 4

n*11 - k*9 + 8 - 4 = 0

n*11 - k*9 + 4 = 0

n = (k*9 - 4)/11

Lo que podemos hacer es evaluar k en distintos valors enteros de tal forma que la solucion de n tambien sea entera. Por ejemplo, si k = 2 tendremos:

n =  (2*9 - 4)/11 = 14/11

Notar que en este caso n no es entero, asi que no sirve.

Seguimos, si k = 9 tendremos:

n = (9*9 - 4)/11 = 77/11 = 7

Ambos son enteros.

Entonces Erica tiene:

L = 9*9 + 4 = 85 libros en total.

Y el numero de estanterias sera el maximo entre n y k, que es k = 9, hay 9 estanterias.

Para colocarlos sin que le sobren, puede colocar 17 libros en cada estanteria. Asi con 5 estanterias colocara los 85 libros.

Answer:

x is 3.

Step-by-step explanation:

Vertically opp angle are equal.

Answer:

x = 25

Step-by-step explanation:

The sum of the angles in a triangle are equal to 180 degrees. Since we know the value of one angle is 90 degrees, subtract 90 from 180 to get 90. Now we know the sum of the other two angles must equal 90 degrees. If we add the x and 2x + 15 together, we get 3x + 15 = 90. Subtract 15 from both sides to get 3x = 75. Divide both sides by 3 to get x = 25.

Answer: the third graph

Step-by-step explanation:

The graph for the equation x+2y = 4 is the third graph in the question.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The graph of the given function is attached with the answer below. When we plot the graph of the equation x+2y = 4 the line cut the y-axis at 2 and the x-axis at 4.

Therefore graph for the equation x+2y = 4 is the third graph in the question.

Answer:

Miranda. Because she earns $10 per hour while Tommy earns $8 per hour.

Step-by-step explanation:

y = 10x <--- 10 is the amount she earns per every x, which is the number of hours she works.

Tommy's equation is y = 8x

Because if you plug in his values of time (x) and total cash earned (y) you get:

32=?4

Read the above ^ as " 32 = blank multiplied by four "

subtract both sides by four to find blank

Our blank equals 8, which is the amount Tommy makes per hour.

CHECK COMPLETE QUESTION BELOW;

sofia wants to rent an apartment. she visits Apartment a charges $200 for one-time deposit and $400 per month for rent. Apartment b charges $500 for a deposit, but only charges $350 per month in rent. Write in inequality that would determine how many months it would take for cumulative amount paid to be less for apartment b

APARTMENT "A"

✓From the question, the one time charge of appartment "a" = $200

and the monthly rent of the appartment = $400

✓ Let denote the number of months as " y"

We can find the TOTAL COST of the rent for apartment "a" as( 200+400y)

TOTAL COST= (200+400y)

APARTMENT "B"

From the question, the one time charge of the appartment is given as $500,The monthly rent of the appartment is given as $350

The total cost of the rent for the apartment can be expressed as (500+350y)

We need to write and solve an inequality that shows how many months it would take for the total paid to be less for apartment b.

Then the total cost of apartment "a" is less than "b" we can expressed it as;

200+400y<500+350y

Collect like terms, we have

400y-350y<500-200

50y<300

y<6

Hence, it takes less than 6 months it would take for the total paid to be less for apartment b.

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

Check the picture I have provided for each letter assigned to a shape.

I noted every shape with letters.

A and C are squares and all 3 B's and E are rectangles.

Now we need to calculate the surface area of every shape in order to find out the area of the whole shape.

The surface area of A and C can be found by using the following formula:[tex]s^{2}[/tex] where s means side.

A = 16×16 = 256

C = 16×16 = 256

The surface area of B and E can be found by using the following formula: w×l where w = width and l = length.

A single B = 16×8 = 128

All 3 B's = 128×3 = 384

E = 16×8 = 128

The area of the main shape is = 256+256+384+128 = 1024 square cm.
