Erica tiene *al menos* 50 libros,su mamá le regala un mueble para acomodar los libros,se coloca 11 libros en cada estantería le sobran 8 y si coloca 9 le sobran 4
Determine la cantidad de estantes y de libros que tiene erica
y de qué forma puede acomodarlo para que no sobre ninguno
Erica tiene 85 libros y 9 estanterias, para colocar todos los libros sin que le sobre ninguno, puede colocar 17 libros en 5 estanterias.
¿Cuantos libros tiene?
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.

help me pls
Answer:
(this is the equation I perceived from your information, if it's not correct make sure to notify me in the comment section below)
3.33x = 55.5*38
Simplify;
3.33x = 2109
Isolate 'x' by applying inverse operations,
The inverse operation of multiplication is division because 3.33 is being multiplied by 'x'.
÷3.33 ÷3.33
x = 633.333..
Answer:
633.333333
Step-by-step explanation:
3.33 x (blank) = 55.5 x 38
55.5 x 38 = 2109
2109 / 3.33 = 633.333333
3.33 x 633.333333 = 55.5 x 38

If x = 8 cm, what is the surface area of the geometric shape formed by this net?
A.
384 square cm
B.
1,024 square cm
C.
768 square cm
D.
192 square cm
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.

What is the value of x
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.

The equation y = 10x describes the amount of money Miranda earns, where x is the number of
hours she works and y is the amount of money she earns.
The table shows the amount of money Tommy earns for different numbers of hours worked.
(a) how much money does miranda earn per hour ? SHOW UR WORK.
(b) who earns more per hour? JUSTIFY YOUR ANSWER .
HELP !! ESPECIALLY IF UR IN k/12. THERES A PICTURE W/ MY 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.
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
Answer:
<6 months
Step-by-step explanation:
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.

mirror is 4x. The side length of the metal frame is 16x. What is the area of the
metal frame?
Answer: [tex]= 240x^2[/tex]
Step-by-step explanation:
Area of the entire frame = [tex](16x)^2 = 256x^2[/tex]
Area of the mirror = area of a circle = [tex]\pi r^2[/tex]
