Answer:
The price for 3 comics is $12.50 and the price for 8 comics is $20.00.
Step-by-step explanation:
To calculate the price of one comic, we can divide the price of the comics by the amount bought:
= $7.50 ÷ 3
= $2.50
Therefore, one comic is $2.50
To figure out how much 5 and 8 comics are, just multiply these numbers by the price of one:
= 5 x $2.50
= $12.50
= 8 x $2.50
= $20.00
The price for 3 comics is $12.50 and the price for 8 comics is $20.00.
4x + y =1
x + 2y = 9
Answer:
x=-1 y=5
Step-by-step explanation:
A. 4x+y=1 multiply the equation negative 2
B. x+2y=9
-8x-2y=-2 add this to equation b
x+2y=9
-7x=7 divide both sides by -7
x=-1
now substitute x for -1 in either of the original equations
-4+y=1 add 4 to both sides
y=5
-4+5=1
-1+10=9

2. La suma de los cuadrados de dos números reales pares consecutivos es 52
Encuentra los números
Answer: ±4 y ±6
Step-by-step explanation:
Algunas definiciones:
Sea N un numero real.
El cuadrado de un numero es:
N^2.
Ahora, nos dicen que N es par, entonces podemos escribir:
N = 2*n
donde n es un numero entero.
Y el par consecutivo a N, va a ser M = N + 2.
M = 2*n + 2.
Entonces:
"La suma de los cuadrados de dos números reales pares consecutivos es 52"
(2n)^2 + (2n + 2)^2 = 52
Tenemos que resolver esto para n.
4n^2 + 4n^2 + 8n + 4 = 52
Entonces tenemos una ecuación cuadrática:
8*n^2 + 8n + 4 - 52 = 0
8*n^2 + 8n - 48 = 0
Antes de usar la ecuación de Bhaskara, dividamos todos los coeficientes por un factor común, en este caso 8 es un factor común:
(8*n^2 + 4n - 48)/8 = n^2 + n - 6 = 0.
Ahora resolvamos esto para n, las dos soluciones son
[tex]n = \frac{-1 +-\sqrt{1^2 - 4*1*-6} }{1*2} = \frac{-1 +- 5 }{2}[/tex]
Entonces las dos soluciones son:
n = (-1 - 5)/2 = -3
n = (-1 + 5)/2 = 2
Entonces, si tomamos la primer solucion, los numeros consecutivos son:
N = 2*-3 = -6
M = N + 2 = -4
Si tomamos la segunda solucion, n = 2.
N = 2*2 = 4.
M = N + 2 = 6.
Entonces podemos concluir que las soluciones son:
±4 y ±6

Polly stacked the tins from five boxes of cat food onto an empty shelf in a supermarket. There were 15 tins of cat food in each box. At the end of the week there were 20 tins left on the shelf. The rest of the tins had been sold. Write the number of boxes of cat food that had been sold, as: (a) A mixed number (b) An improper fraction
Answer:
(a) [tex]3\frac{2}{3}[/tex] boxes of cat food had been sold.
(b) [tex]\frac{11}{3}[/tex] boxes of cat food had been sold.
Step-by-step explanation:
From the question,
Polly stacked the tins from five boxes of cat food onto an empty shelf and there were 15 tins of cat food in each box. That is,
5 × 15 tins of cat food were stacked onto the empty shelf.
5 × 15 = 75
Hence, 75 tins of cat food were stacked onto the empty shelf.
Also, from the question,
At the end of the week there were 20 tins left on the shelf and the rest of the tins had been sold, that is
75 - 20 tins had been sold
75 - 20 = 55
Hence, 55 tins of cat food had been sold.
To determine the number of boxes of cat food that had been sold,
Since there are 15 tins of cat food per box, then
we will divide 55 tins of cat food that had been sold by 15 tins of cat food per box
55 ÷ 15 = [tex]\frac{55}{15}[/tex]
Hence, [tex]\frac{55}{15}[/tex] boxes of cat food had been sold
(a) As a mixed number
[tex]\frac{55}{15} = 3\frac{2}{3}[/tex]
Hence, [tex]3\frac{2}{3}[/tex] boxes of cat food had been sold.
(b) As an improper fraction
[tex]\frac{55}{15} = \frac{11}{3}[/tex]
Hence, [tex]\frac{11}{3}[/tex] boxes of cat food had been sold.
A local band is being paid $250 for performing, they receive $2 for each ticket sold.
The chart shows the bands total pay for the first 5 tickets sold.
Tickets sold: Bands pay
1 $250+$2(1)
2 $250+$2(2)
3 $250+$2(3). 4 $250+$2(4)
5 $250+$2(5)
Write an expression for the bands total pay for x number of tickets sold.
Answer:
$250+$2(x) = Total amount paid
Step-by-step explanation:
$250 is the initial amount. They earn $2 per person. The $250 is a flat amount that doesn't change. $2 is paid per person, so you multiply $2 by the amount of tickets sold.
$250 + $2(x) = Total amount paid
what is the equation of the line that contains the points (3,5) and (7,9)
Answer:
y=x+2
Step-by-step explanation:
The required equation of line will be y = x + 2.
It is given that a line contains points (3,5) and (4,9).
We have to find out the equation of the line.
What is the general equation of a line ?
The equation of a line is y = mx + c.
As per the question line contains points ;
(x1,y1) = (3,5) and (x2,y2) = (7,9) .
Using these points, firstly , we need to find the value of m ;
∵ m = ( y2-y1) / (x2-x1)
m = ( 9-5) / (7-3)
m = 4 / 4
m = 1
We now need to find out the value of c.
Since , (7,9) is on the line this meant this meant value of c is 2.
Putting the value of m and c in general equation of line i.e., y= mx + c
y = 1 × x + 2
y= x + 2

Q5. A car is bought for £5000 and sold for £7500.
What is the percentage profit?
Answer:
50% profit
Step-by-step explanation:
Cost price = £ 5000
Selling price = £ 7500
Profit = Selling price - cost price
= 7500 - 5000
= £ 2500
Profit percentage = [tex]\frac{2500}{5000}*100[/tex]

Robert conducts an experiment to measure the temperature of a solution. Due to a defect in the apparatus, the temperature of the solution measured in each trial is 5°F more or less than the theoretical temperature of 11°F of the solution.
The following absolute value equation can be used to determine the temperature of the solution measured by Robert:
|x − 11| = 5.
Here, x represents the measured temperature of the solution in degrees Fahrenheit.
Based on the above information, what is the temperature of the solution as measured by Robert?
A.
The temperature of the solution measured by Robert is 5°F or 6°F.
B.
The temperature of the solution measured by Robert is -6°F or 6°F.
C.
The temperature of the solution measured by Robert is -6°F or -16°F.
D.
The temperature of the solution measured by Robert is 16°F or 6°F.
What is the coordinate of point P on the line segment AB that is 3/4 of the distance from A to B for A(2,5) and B(6,9)?
Answer:
p is (3.71, 6.71)
Step-by-step explanation:
Given that p is at the distance of 3/4 from A to B
it mean that point p divides the line AB into 3:4 ratio.
and
if there are two points (x1,y1) and (x2,y22) which is divided by point p in the ratio m:n then
coordinates of point p (x,y) is given
p (x = (n*x1+m*x2)/m+n , y = (n*y1+m*y2)/m+n )
________________________________________________
Given the points AB
A(2,5)
B(6,9)
m:n = 3:4
thus,
p (x = (4*2+3*6)/7 , y = (4*5+3*9)/7 )
p (x = (4*2+3*6)/7 , y = (4*5+3*9)/7 )
p (x = (26/7 , y = 47/7 )
P ( x = 3.71, y = 6.71)
Thus, coordinates of point p is (3.71, 6.71) which is at 3/4 of the distance from A to B for A(2,5) and B(6,9)/

What algebraic expression could represent the average of 2x, x + 3, and 6x?
Answer:
3x+1
Step-by-step explanation:
(2x+x+3+6x)/3
9x+3/3
3x+1
The final result is a simplified algebraic expression 3x + 1 that represents the average of 2x, x + 3, and 6x.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The average of 2x, x + 3, and 6x can be represented by the algebraic expression (2x + (x + 3) + 6x)/3.
This expression takes the sum of 2x, x + 3, and 6x, and then divides that sum by 3, which is the number of terms being averaged.
Alternatively, the average can be represented by (2x + x + 6x + 3) / 3 = (9x + 3) / 3 = 3x + 1.
In either case, the final result is a simplified algebraic expression that represents the average of 2x, x + 3, and 6x.

The Huggins family went out to dinner. The price of the meal was $62.95. The sales tax is 8% of the
price of the meal. The tip is 15% of the meal and the sales tax. How much money did the family
pay for the meal, including tax and tip?
Answer:
$62.95 (meal) + $5.03 (sales tax) +$.75 (sales tax tip) + $9.44 (meal tip)
Total: $78.17
Answer:
$78.19
Step-by-step explanation:
To find the total after the sales tax is charged you have to do
$62.95 x 1.08 (1 = to the total and .08 to add sales tax value) =$67.986 round*
Now you take $67.99 (has been rounded) and multiply but .15 to find out what is 15% of $67.99 , it comes out to be 10.1979 (Round)
Now to finish you add $67.99 +$10.20 = $78.19
