White raven [17]
Well this isn't college math lol

You do 19x + 13x + 4x = 26x

180 divided by 26x =        x = 6.92307...

plug in x then  round to tenth

6.9 x 19 = 131.1 degrees

6.9 x 13 = 89.7 degrees

6.9 x 4 = 27.6 degrees

Each car in a rental fleet is either red or white, and there are 75 cars total. There are three more white than twice the number
professor190 [17]
Number of red cars = x
Number of white cars = y

x + y = 75
y + 3 = 2x

x + y = 75
y = 75 - x

(75 - x) + 3 = 2x
78 = 3x
26 = x

y + 3 = 2(26)
y + 3 = 52
y = 49

There are 49 white cars.

Anvisha [2.4K]

Answer:

Los gastos totales en los que incurre Carla = (36x + 28y + 3z) pesos

Step-by-step explanation:

A partir de la pregunta, a continuación se proporciona la cantidad de elementos necesarios:

21 lápices, 8 carpetas, 3 broches, 10 resaltadores, 6 blocs de notas adhesivas y 9 rotuladores.

Los precios de cada artículo se dan a continuación

Precio de cada lápiz = x pesos

Precio de cada carpeta = y pesos

Precio de cada broche = z pesos

El precio de cada resaltador es el doble que el de cada carpeta

= 2 × y pesos

= 2y pesos

El precio de cada barra de notas adhesivas es el doble del precio de cada lápiz

= 2 × x pesos

= 2x pesos

El precio de cada marcador (bolígrafo) es el triple del precio de cada lápiz.

= 3 × x pesos

= 3x pesos

Indique el gasto total en el que incurrirá Carla.

Los gastos totales en los que incurrirá Carla =

(21 × x pesos) + (8 × y pesos) + (3 × z pesos) + (10 × 2y pesos) + (6 × x pesos) + (9 × x pesos)

= (21x + 8y + 3z + 20y + 6x + 9x) pesos

Recopilar términos similares

= (21x + 6x + 9x + 8y + 20y + 3z) pesos

= (36x + 28y + 3z) pesos

Por lo tanto, los gastos totales en los que incurre Carla = (36x + 28y + 3z) pesos
