Answer:
-5v+4
Step-by-step explanation:
Remove the parentheses and combine the like terms:
-2v + (-4) + 8 + (-3v)
-2v -4 + 8 -3v [Remove parentheses]
-5v +4 [Combine like terms]
<u>-5v +4 </u>
3/5 because the p's cancel out
Answer:
x = 24 minutos
Step-by-step explanation:
Llamaremos "y" el costo fijo mensual y "x" la cantidad de minutos consumidos al mes, según lo cual:
El enunciado del problema establece que la facturación en pesos es igual a un costo fijo y más el consumo en minutos del mes, entonces
En Abril 52,50 = y + b*x ⇒ 52,5 = y + 69*b
y en Mayo 32 = y + b*x ⇒ 32 = y + 28*b
Así obtuvimos un sistema de dos ecuaciones con dos incógnitas, que resolveremos y obtendremos los valores de b y de y
y = 52,50 - 69*b
32 = ( 52,50 - 69*b ) + 28*b
- 20,50 = - 41*b
b = 0,5
y y = 52,5 - 69*0,5
y = 18
Entonces la ecuación de facturación es :
F(x) = 18 + 0,5*x
Para pagar como máximo 30 pesos en el mes siguiente
F(x) = 30 = 18 + 0,5*x
30 - 18 = 0,5*x
x = 24 minutos
Answer:
The total income of designer from this work is $1649.6.
Step-by-step explanation:
The fees charged by the designer = $1600
The commission on total sales = 8%
Total sales amount in the festival = $620
Now, 8% of $620 =
So, the commission on total sales = $49.6
Also, Total Income of the designer = Deign Fee + 8% Commission fee
= $1600 + $49.6
= $1649.6
Hence, the total income of designer from this work is $1649.6.
Answer:
C = 5x + 8y + 15z + 1.5r + 15
Where C = cost for the family of 6
Step-by-step explanation:
Let:
x = number of children under 10
y = number of children 11-16
z = number of all others (16 and above)
r = number of rides
Cost:
Under 10 = $5
11-16 = $8
Above 16 = $15
Ticket Ride = $1.50
We have an additional $15 for parking
So from there, we can find the cost by getting the total:
Cost for each TOTAL
x x $5 $5x
y x $8 $8y
z x $15 $15z
r x $1.50 $1.50r
Constant : $15 for parking
So the expression would then be:
C = 5x + 8y + 15z + 1.5r + 15
Given:
6 family members
x = 3
y = 1
z = 2
r = 5
We fill in the formula
C = 5x + 8y + 15z + 1.5r + 15
C = 5(3) + 8(1) + 15(2) + 1.5(5) + 15
C = 15 + 8 + 30 + 7.5 + 15
C = 75.50
