5.95 + 2.95 = 8.9
8.9 + 29.95 = 38.85
62.35 - 38.85 = 23.5 
So Daniel spent $23.50 on long distance calling

Answer: Daniel spent $23.5 on long distance

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given.

So, Daniel's total bill (62.35) is equal to the sum of the cost of all the services: Basic cell phone rate (29.95); voice mail (5.95); text messaging (2.95); long distance (C)

Mathematically speaking:

29.95+5.95+2.95+C = 62.35

Solving for C

38.85+C =62.35

C =62.35-38.85

C =$23.5

Daniel spent $23.5 on long distance

PLEASE HELP I DONT UNDERSTAND ILL GIVE MORE IF ITS RIGHT
andre [41]

Answer:

120

Step-by-step explanation:

The prism shown is a triangular prism

The volume of a triangular prism can be found by multiplying the area of the base ( which is a triangle ) by the length of the prism ( which is 10 feet )

First let's find the area of the base.

To find the area of a triangle we use this formula A=\frac{bh}{2}

where b = base length and h = height

The base length is 6ft and the height is 4ft.

Using these dimensions we plug in the values into the formula

\frac{4*6}{2} \\4*6=24\\\frac{24}{2} =12

So the area of the base is 12ft²

Finally to find the volume we multiply the area of the base by the length of the prism

12 * 10 = 120

Hence, the volume of the prism is 120ft³

How do you write 3x-y=14 in slope intercept form
Ede4ka [16]
Y=3x-14 or 3x-14=Y
This is because you want to keep y positive, and so you add Y on both sides and get 3x=14+y, then you want to get y alone so you subtract 14 on both sides and get 3x-14=Y

Un hotel alquiló 108 habitaciones, dobles e individuales. El costo de habitación doble por noche es $78 y de habitación individu
Triss [41]
I have to assume that you want the answer in Spanish *but without using accents).

Usa las siguientes variables:

d = numero de habitaciones dobles

i = numero de habitaciones individuales

Por la primera premisa:

d + i = 180

Por la segunda premisa, los costos son tales que:

78d + 72i = 7839

Para resolver ese sistema podemos despejar una de las variables de la primera ecucacion y sustituir en la segunda:

i = 180 - d

78d + 72 (180 - d) = 7839

78d + 12960 - 72d = 7839

De aqui ya veo que va a dar un numero negativo para el numero de habitaciones dobles, asi que supongo que algun dato en el enunciado esta equivocado.

6d = 7839 - 12960 = -5121

=> d = -5121 / 6 = - 853.5


Al corregir los datos podras seguir el procedimiento que te he explicado para encontrar la solucion.
