Ingrid collected 6 cans of food and 18 boxes of food for the food bank. Which describes the relationship between cans of food and boxes of food? Ingrid collected 3 times as many cans as she did boxes. For every 6 boxes of food Ingrid collected, she also collected 18 cans of food. For every 18 boxes of food Ingrid collected, she also collected 24 cans of food. Ingrid collected 3 times as many boxes as she did cans.
Answer:
Ingrid collected 3 times as many Food boxes as she did cans of Food.
Step-by-step explanation:
Ingrid collected 6 cans of food from the food bank.
Ingrid collected 18 boxes of food from the food bank.
In order to determine the relationship
let cans of food = x = 6
So the boxes of food will be 3x = 3*6 = 18
So the relation between Cans of food and boxes of food will be
Ingrid collected 3 times as many boxes as she did cans

Find the difference.
10 - 12
Answer:
-2
Step-by-step explanation:
12 is the larger number so if you take a bigger number and subtract it from a smaller number you get negative
The value of the difference 10 - 12 is -2.
The difference between 10 and 12 is calculated by subtracting the smaller number from the larger number.
We have to find difference of 10 - 12.
When we subtract 12 from 10, we get a result of -2.
The negative sign indicates that 12 is greater than 10, and the absolute value of 2 represents the numerical difference between the two numbers.
So, the difference between 10 and 12 is -2.

La suma de las edades de un padre y sus dos hijos es de 48 dentro de 10 años el doble de la suma de las edades de los hijos excederá en 6 años a las edades del padre cuando nacio el pequeño la edad del padre accedia 26 unidades al triple de la edad que tenia el hijo mayor cual es la edad de los 3
Answer:
La edad del padre es 40 años, la edad del hijo menor es 2 años y la del hijo mayor es 6 años.
Step-by-step explanation:
Un sistema de ecuaciones lineales es un conjunto de ecuaciones lineales que tienen más de una incógnita. Las incógnitas aparecen en varias de las ecuaciones, pero no necesariamente en todas, y se relacionan mediante las ecuaciones. En otras palabras, un sistema de ecuaciones es un conjunto de dos o más ecuaciones con varias incógnitas en la que desea encontrar una solución común, es decir, encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.
En este caso debes resolver una sistema de ecuaciones, para lo cual debes en primer lugar definir las variables a utilizar:
x: edad del padre y: edad del hijo mayor z: edad del hijo menorEntonces, siendo:
La suma de las edades de un padre y sus 2 hijos es 48. Dentro de 10 años el doble de la suma de las edades de los hijos excederá en 6 años a la edad del padre. Cuando nació el pequeño la edad del padre excede 26 unidades al triple de la edad que tenía el hijo mayor.Se puede expresar simbólicamente como:
x +y +z= 48 Ecuación 12*[(y+10) + (z+10)]= (x+10) + 6 Ecuación 2(x-z)= 3*(y-z) +26 Ecuación 3que será el sistema de ecuaciones a resolver.
Para resolver se puede usar el método de sustitución, que consiste en despejar o aislar una de las incógnitas (por ejemplo, x ) y sustituir su expresión en la otra ecuación para así ir determinando el valor de cada una de las variables.
En este caso, despejando el valor de x de la ecuación 1 se obtiene:
x= 48 -y -z Ecuación 4
Reemplazando esta expresión en la ecuación 2:
2*[(y+10) + (z+10)]= (48 -y -z+10) + 6
y aislando la variable y obtienes:
2*[y + z +10 +10]= 48 -y -z +10 +6
2*[y + z +20]= 64 -y -z
2*y + 2*z +40= 64 -y -z
2*y + y= 64 -z -2*z -40
3*y= 24 - 3*z
y= (24 - 3*z)÷ 3
y= 8 - z Ecuación 5
Reemplazando esta expresión en la ecuación 4:
x= 48 - (8 -z) -z
y resolviendo se obtiene el valor de x, es decir, la edad del padre:
x= 48 -8 +z +z
x=40
Entonces, la edad del padre es 40 años.
Ahora, reemplazando la ecuación 5 y el valor de x en la ecuación 3 se obtiene:
(40-z)= 3*(8 -z -z) +26
Resolviendo:
40 -z= 3*(8 -2*z) +26
40 -z= 3*8 - 3*2*z +26
40 -z= 24 -6*z +26
-z + 6*z= 24 + 26 - 40
5*z= 10
z= 10÷ 5
z=2
Entonces, la edad del hijo menor es 2 años.
Finalmente, reemplazando el valor de z en la ecuación 5 se obtiene:
y= 8 - 2
y= 6
Por lo que, la edad del hijo mayor es 6 años.

34x+85=3(13x+7)
Step 1: Simplify both sides of the equation.
34x+85=3(13x+7)
34x+85=(3)(13x)+(3)(7)(Distribute)
34x+85=39x+21
Step 2: Subtract 39x from both sides.
34x+85−39x=39x+21−39x
−5x+85=21
Step 3: Subtract 85 from both sides.
−5x+85−85=21−85
−5x=−64
Step 4: Divide both sides by -5.
−5x/−5=−64/−5
x=64/5

On Saturday, Carrie went to the store and bought 4 loaves of bread and 1 gallon of milk for a total of $12.50. The next weekend, she went to the same store and spent $11.50 on 2 loaves of bread and 2 gallons of milk. The prices had not changed. What is the price for one gallon of milk?
Answer:
The price of one gallon of milk is $3.5
Step-by-step explanation:
x----> the price of one loaves of bread
y----> the price of one gallon of milk
we know that
4x+y=12.50 ----> equation A
2x+2y=11.50 ----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2.25,3.5)
see the attached figure
therefore
The price of one loaves of bread is $2.25
The price of one gallon of milk is $3.5

where L = length = 8
W = width = 2
H = height = 2
plugin values into the formula:
surface area = 2 (8*2 + 8*2 + 2*2)

b)
where L = length = 2
W = width = 3
H = height = 9
plugin values into the formula:
surface area = 2 (2*3 + 2*9 + 3*9)
= 2 (6 + 18 + 27)
= 102

c)
surface area = 2(area of rectangular side) + 2(area of triangular side) + base area
plugin values into the formula:
surface area = 2 (2*7) + 2( 1/2 * 7 * 6.1) + (2*7)

Answer:
[tex]75 {x}^{ \frac{3}{2} } {y}^{6} {z}^{ \frac{11}{2} } [/tex]
Step-by-step explanation:
First thing is to multiply. We don't need to bother with the root for now.
[tex] \sqrt{15 {x}^{2} {y}^{11} {z}^{4} } \times \sqrt{5xy {z}^{7} } = \\ \sqrt{75 {x}^{3} {y}^{12} {z}^{11} } [/tex]
All I did was multiply the numbers and added the exponents for the variables.
Now all we have to do is divide the exponents in half for the variables, nothing is needed additionally for the 75.
[tex]75 {x}^{ \frac{3}{2} } {y}^{6} {z}^{ \frac{11}{2} }[/tex]
There you go, just a few steps and you have your answer.
You can simplify further by moving the answer for the root infront of the square root so it isn't as sloppy. This would make the simplest for to be

Angel is running for school council president. He receives 300 votes, which is 60% of all the votes. How many students vote in the election?
Angel receives 300 votes which is 60% of total votes.
Therefore we can determine 60% = 300
The next thing to do would be to determine 1% and we can do this by dividing both sides by 60:
60% = 300
1% = 5
Then multiply both sides by 100 to determine 100% of total votes (total amount of students who voted):
1% = 5
100% = 500
Therefore 500 students voted in the election.
Answer:
500 students
Step-by-step explanation:
300=60%
300x2=600
(turning the 300 into 600 helps it make sense)
600/3=200
200x5= 1000
1000/2=500
Determine the scale factor for the following points: (4, 2) to (16, 8)
Answer:
The rule of dilation by a scale factor 4 is:
(x, y) → (4x, 4y)
P(4, 2) → (4x, 4y) = (4(4), 4(2)) = P'(16, 8)
Therefore, 4 will be the scale factor.
Step-by-step explanation:
Given the point
(4, 2)As the image coordinates of (4, 2) are (16, 8) after the scale factor, we need to determine what could be the scale factor.
Let P(4, 2) is the original point, and P'(16, 8) is the image of the point P(4, 2).It is clear that the coordinates of the image P'(16, 8) are 4 times the coordinates of the original point P(4, 2), which means the point P(4, 2) is dilated by a scale factor of 4.
Thus, the rule of dilation by a scale factor 4 is:
(x, y) → (4x, 4y)
P(4, 2) → (4x, 4y) = (4(4), 4(2)) = P'(16, 8)
Therefore, 4 will be the scale factor.
