Ayuda con esto tengo muchos deberes y nececito terminarlos ahora, por favor ayuda :( .María y Nancy son vecinas, y todas estas semanas han realizado compras en el mercado. La semana pasada María gastó 25,75 dólares, exactamente 3 veces más de lo que gastó Nancy, que tenía poco que comprar. ¿Cuánto dinero se gastó Nancy?
Answer:
Nancy gastó 8,58 dólares.
Step-by-step explanation:
Para calcular cuánto dinero gastó Nancy, debemos hallar la relación entre Nancy y María, tal como sigue:
[tex] M = 3N [/tex] (1)
En donde M es por María y N por Nancy
En la relación de la equación (1) tenemos que el dinero que gastó María es 3 veces lo que gastó Nancy, tal como dice el enunciado.
Entonces, podemos hallar ahora cuánto gastó Nancy:
[tex] N = \frac{M}{3} = \frac{25,75}{3} = 8,58 [/tex]
Por lo tanto, Nancy gastó 8,58 dólares.

Help me for a brainllest. A theater holds 2,680 seats. The lower level has 100 less than 2 times as many seats as the upper level. The middle level has 80 more than 3 times as many seats as the upper level. How many seats are in the middle level?
Answer: 1430
Step-by-step explanation: x + y + z = 2680
x = 2z - 100
y = 3z + 80
x + y = 5z - 20
6z - 20 = 2680
z = 450
y = 1430
Solution:
x = 800, y = 1430, z = 450
Answer:
1430

Xavier is driving home. He starts 250 miles from home and his car can travel 28 miles per gallon of gasoline he uses. Xavier stops at a rest stop that is 100 miles from home. Let g be the amount or gas he has used at that point. Set up and solve an equation for how much gas Xavier used to get to the rest stop.
Answer:
For 100 miles he uses 3.571 gallons of gasoline.
In equation form it is y/x*100
Step-by-step explanation:
Unitary Method
He travels 28 miles per gallon of gasoline.
For 1 mile he uses 1/28 gallons
For 100 miles he uses 1/28 * 100= 100/28= 3.571 gallons of gasoline.
Let x be the miles and y be the gallons of gasoline used to travel x miles.
Then for 1 mile the gallons of gasoline used will be y/ x gallons.
For 100 miles the gallons of gasoline used will be y/x *100 gallons.
In equation form it is y/x*100 gallons for 100 miles where x is the number of miles and y is the amount of gallons.

A shipping company sells a rectangular box with dimensions of 12
inches by 12 inches by 18 inches. Find the length of the longest
diagonal in the box.
24.7.
24.8
O 288
0 612
Answer:
24.7 inches
Step-by-step explanation:
Length = 18 inches
Width = 12 inches
Height = 12 inches
Length of the longest diagonal,d = length^2 + width^2 + height^2
d^2 = 18^2 + 12^2 + 12^2
d^2 = 324 + 144 + 144
d^2 = 612
d = √612
= 24.7 of inches
Length of the longest diagonal in the box = 24.7 inches
A company orders 24 boxed lunches from a deli for $238.80. If each boxed lunch costs the same amount, what is the unit cost of each boxed lunch?
Answer:
$9.95
Step-by-step explanation:
$238.80 ÷ 24 = $9.95
$238.80 ⇾ The final cost of boxed lunches altogether.
24 ⇾ The number of boxed lunches bought.
$9.95 ⇾ The unit price of boxed lunches after dividing the final cost($238.80) by the amount bought(24).
Hope this wasn't confusing. o(^▽^)o
