C or D
Step-by-step explanation:
Marcus is buying taco shells for a party. There will be 13 adults and 17 children
attending the party. He plans to make 3 tacos for each adult and 1 taco for each child.
There are 8 taco shells in each package. How many packages of taco shells will Marcus
need to buy in order to have enough tacos for the people attending the party?
A 7, because (13 x 3 + 17) + 8 = 7
B 28, because (13 x 17 + 3) = 8 = 28
C 80, because (13 + 17) x 8 = 3 = 80
D 15, because (13 + 17 x 4) + 8 = 15
Answer:
Tacos for adults: 13*3
Tacos for children: 17*1
Total: 39+17
=56
And in each package there will be 8 tacos
So, 56/8 = 7 = No. of tacos needed.
So the corrrect answer is A 7, because (13 x 3 + 17) + 8 = 7

30 POINTS AND WILL MARK BRAINLY Graph the line that passes through the points (-3,-8) and (2,-3) and determine the equation of the line
Answer:
y = x - 5 :)
Step-by-step explanation:
use point-slope form to create an equation for this line.
find the slope first by subtracting the y-values from each other, and the x-values from each other.
-3-(-8) = 5 <- y-value
2-(-3) = 5 <- x-value
5/5 = 1 <- slope
plug the slope and one of the points into the point-slope equation.
y - (-3) = 1(x - 2)
y + 3 = x - 2
subtract 3 from both sides.
y = x - 5
graph this by placing a point on -5 on the y-axis, and going up by 1 and right by 1 for the slope of 1.
hope this helped! xoxxo
Step-by-step explanation:
Hey there!
The line passes through points; (-3,-8) and (2,-3).
Now; use formula for double point.
[tex](y - y1) = \frac{y2 - y2}{x2 - x1} (x - x1)[/tex]
Put all values.
[tex](y + 8) = \frac{ - 3 + 8}{2 + 3} (x + 3)[/tex]
Simplify it.
[tex](y + 8) = \frac{5}{5} (x + 3)[/tex]
[tex]y = x + 3 - 8[/tex]
[tex]y = x - 5[/tex]
Therefore, the equation is y= x-5.
Hope it helps...

roberto garcia ha jugado en las ligas menores durante 11 años. el total de jonrones en cada año ha sido de: 56,62,49,65,58,52,68,72,25,64. ¿Cuantos jonrones necesita Roberto para que la próxima temporada pueda tener una media de 60 en 12 años?
Los puntos de datos dados son 10
Responder:
89 jonrones
Explicación paso a paso:
Dados los datos:
Datos de jonrones durante 11 años:
56,62,49,65,58,52,68,72,25,64
Para promediar 60 jonrones en 12 años:
Tome la media de los datos, utilizando una incógnita para el Número de jonrones en el año 12:
[(56 + 62 + 49 + 65 + 58 + 52 + 68 + 72 + 25 + 64 x) / 11] = 60
[(571 + x) / 11] = 60
571 + x = 60 * 11
571 + x = 660
x = 660 - 571
x = 89
Given; D is the Midpoint of CE / Prove DE =1/2CE
Answer:
Check explanation
Step-by-step explanation:
Here, we want to make a prove;
Mathematically , since D is the midpoint of CE
Then;
CE = CD + DE
Also, since D splits the line segment into two equal parts as the midpoint, then CD must be equal to DE
I.e CD = DE
Hence, we can express CE as follows;
CE = DE + DE
CE = 2 DE
Divide both sides by 2
CE/2 = DE
Hence; DE = 1/2 CE

Two car rental companies charge an initial rental fee plus a fee per day. The table shows the total costs of renting a car for x days from
Discount Car Rentals. The total costy (in dollars) of renting a car for x days from Pay Less Rentals is represented by the equation
y=25x + 170. Which rental company charges less per day? How many days must you rent a car for the total costs to be the same?
Answer:
Step-by-step explanation:
Two car rental companies charge an initial rental fee and a fee per day.
Total cost for the company A is given by the equation,
y = 25x + 170
Car A charges $25 per day. [Slope of the line]
Another car rental company B charges as per table attached.
Per day car rental for the company B = [tex]\frac{270-180}{4-2}[/tex]
= [tex]\frac{90}{2}[/tex]
= $45 per day
Therefore, per day rental charged by company A is less.
Let the equation for the car rental by company A is,
y = mx + b
where m = per day rental charged by company A = $21.5
y = 45x + b
One point (2, 180) from the table lies on the equation.
Therefore, 180 = 45(2) + b
b = 180 - 90
b = 90
So the equation will be,
y = 45x + 90
If both the company charge the same after x day of rental,
45x + 90 = 25x + 170
45x - 25x = 170 - 90
20x = 80
x = 4
After 4 days car rentals for both the companies will be same.

Solve by factoring:
x² – 5x - 14=0
O A. x = 7,X = -2
B. x = -7, x = 2
O C. x = -1, x = 14
O D. x=-14, x = 1
Answer ASAP!
Answer:
A
Step-by-step explanation:
Given
x² - 5x - 14 = 0
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)
The factors are - 7 and + 2, since
- 7 × 2 = - 14 and - 7 + 2 = - 5, thus
(x - 7)(x + 2) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 2 = 0 ⇒ x = - 2

What is the reciprocal of 2 and 9 over 10?
Answer:
Part A: [tex]\frac{1}{2}[/tex]
Part B: [tex]\frac{10}{9}[/tex]
Step-by-step explanation:
Part A: What is the reciprocal of 2.
2 is just [tex]\frac{2}{1}[/tex] in fraction terms. To find the reciprocal, you just have to flip it over. That would get to [tex]\frac{1}{2}[/tex]. Therefore, the reciprocal is [tex]\frac{1}{2}[/tex].
Part B: What is the reciprocal of 9 over 10?
9 over 10 in numerical terms is just [tex]\frac{9}{10}[/tex]. o find the reciprocal, you just have to flip it over. That would get to [tex]\frac{10}{9}[/tex]. Therefore, the reciprocal is [tex]\frac{10}{9}[/tex].
