Answer:
14 buses and 5 vansStep-by-step explanation:
Let the number of buses be x and vans be y.
Equations as per given:
x + y = 1925x + 7y = 385Substitute y and solve for x the second equation:
y = 19 - x25x + 7(19 - x) = 38525x - 7x + 133 = 38518x = 385 - 13318x = 252x = 252/18x = 14Then finding y:
y = 19 - 14 = 5The answer is 14 buses and 5 vans

Bob buys lunch at Chick Fil A for his friends on Tuesday. He buys 9 sandwiches and 5 drinks
and pays $44 total. Ben buys lunch on Friday and pays $70 for 15 sandwiches and 7 drinks.
What is the price for a sandwich and what is the price for a drink?
Answer:
A sandwich is $3.50 and the price of a drink is $2.50
Step-by-step explanation:
Create a system of equations where s is the price of a sandwich and d is the price of a drink:
9s + 5d = 44
15s + 7d = 70
Solve by elimination by multiplying the top equation by 7 and the bottom equation by -5, then adding them together:
63s + 35d = 308
-75s - 35d = -350
Add them together:
-12s = -42
s = 3.5
Then, plug in 3.5 as s into one of the equations to solve for d:
9s + 5d = 44
9(3.5) + 5d = 44
31.5 + 5d = 44
5d = 12.5
d = 2.5
So, a sandwich is $3.50 and the price of a drink is $2.50
Answer:
A sandwich is $3.50 and the price of a drink is $2.50

solve for n. n/-5= 7
Answer:
n = -35
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
n/-5 = 7
Step 2: Solve for n
Multiply both sides by -5: n = -35Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: -35/-5 = 7Divide: 7 = 7Here we see that 7 does indeed equal 7.
∴ n = -35 is a solution to the equation.

La Sra.Elena y el Sr.Eulalio,abortan taxis diferentes de la misma empresa el costo del servicio es un importe fijo de salida (banderazo) mas otra cantidad por los kilometros recorridos.Si la SraElena paga $190 por recorrer 8 km y el Sr Eulalio paga $130 por correr 5 km calcular el costo de banderazo y el costo por kilometro recorrido
Answer:
$ 30
$ 20
Step-by-step explanation:
Sea el costo fijo xy el costo por km sea y suponiendo que es el mismo para ambos taxis.
De la pregunta obtenemos las dos ecuaciones
[tex]x+8y=190\quad ...(i)[/tex]
[tex]x+5y=130\quad ...(ii)[/tex]
Aplicando [tex](i)-(ii)[/tex]
[tex]8y-5y=190-130\\\Rightarrow 3y=60\\\Rightarrow y=\dfrac{60}{3}\\\Rightarrow y=20[/tex]
Sustituyendo en [tex](ii)[/tex]
[tex]x+5y=130\\\Rightarrow x+5\times 20=130\\\Rightarrow x=130-100\\\Rightarrow x=30[/tex]
Entonces, el costo fijo es de $ 30 y el costo por km es de $ 20.

Lola's puppy weighed 19 ounces on the second visit the puppy had gained 9 ounces on the third visit the puppy heaven gained another 7 ounces what is the percent increase since the first visit and the puppy weighed around to the nearest percent
Answer:
84%
Step-by-step explanation:
In order to calculate this, we first need to calculate the total weight of the puppy on the last visit. We do this by adding the weight that the puppy gained each visit like so...
19oz + 9oz + 7oz = 35oz
Now that we have the final weight we simply divide the final weight by the initial weight of the puppy in the first visit. Then we subtract 1 from that value and multiply by 100 to get the percentage increase.
35oz / 19oz = 1.84
1.84 - 1 = 0.84
0.84 * 100 = 84%
Finally, we can see that the puppy had an 84% increase since the first visit.

Consider the line y=-2/7x-7
and the point is (-7,-4) what would the perpendicular line be and the parallel be
Answer:
a) The equation of line perpendicular to above line and passes through point (-7,-4) is [tex]\mathbf{y=\frac{7}{2}x+\frac{41}{2}}[/tex]
b) The equation of line parallel to above line and passes through point (-7,-4) is [tex]\mathbf{y=-\frac{2}{7}x-6}[/tex]
Step-by-step explanation:
We are given the line: [tex]y=-\frac{2}{7}x-7[/tex]
The slope of the above equation is: [tex]m=-\frac{2}{7}[/tex] (By comparing with general form [tex]y=mx+b[/tex] where m is slope)
a) Find equation of line perpendicular to above line and passes through point (-7,-4)
If two lines are perpendicular there slopes are opposite reciprocal i.e [tex]m_1=-\frac{1}{m_2}[/tex]
The slope of new line will be: [tex]m = \frac{7}{2}[/tex]
Now finding y-intercept using slope and point (-7,-4)
[tex]y=mx+b\\-4=\frac{7}{2}(-7)+b \\-4=\frac{-49}{2}+b \\b=-4+\frac{49}{2}\\b=\frac{-8+49}{2}\\b=\frac{41}{2}[/tex]
So, the equation of line perpendicular to above line and passes through point (-7,-4) will be:
[tex]y=mx+b\\y=\frac{7}{2}x+\frac{41}{2}[/tex]
So, the equation of line perpendicular to above line and passes through point (-7,-4) is [tex]\mathbf{y=\frac{7}{2}x+\frac{41}{2}}[/tex]
b) Find equation of line parallel to above line and passes through point (-7,-4)
If two lines are parallel there slopes are same i.e [tex]m_1=m_2[/tex]
The slope of new line will be: [tex]m = -\frac{2}{7}[/tex]
Now finding y-intercept using slope and point (-7,-4)
[tex]y=mx+b\\-4=-\frac{2}{7}(-7)+b \\-4=-2(-1)+b\\-4=+2+b \\b=-4-2\\b=-6[/tex]
So, the equation of line parallel to above line and passes through point (-7,-4) will be:
[tex]y=mx+b\\y=-\frac{2}{7}x-6[/tex]
So, the equation of line parallel to above line and passes through point (-7,-4) is [tex]\mathbf{y=-\frac{2}{7}x-6}[/tex]
The line that passes through (2, 4) and (0, 8) can be expressed by which of the following
Answer:
The first one and the second one
