There are 7 numbers.  7 X 45 equals 315.  40+45+48+54+45=232.
315-232=83.

The 2 numbers can each have different values, such as 41 and 42, or 40 and 43.  The numbers must add up to 83, though.

Las+salchichas+vienen+en+paquetes+de+6+y+los+panes+para+panchos+se+envasan+en+paquetes+de+8+unidades+¿Es+cierto+que+si+se+prepar
vovikov84 [41]

Answer:

Es cierto se usan 16 paquetes de salchichas y 12 paquetes de panes para pancho.

Step-by-step explanation:

Lo que debemos hacer en este caso es dividir la cantidad total de panchos primero por la cantidad de unidades de salchichas que vienen en su paquete y segundo por la cantidad de unidades de panes para panchos que vienen en su paquete, si el resultado nos da un numero entero podemos decir que usa una cantidad completa de paquetes de salchichas y de panes:

96/6 = 16

96/8 = 12

Es decir que para 96 panchos se usan 16 paquetes de salchichas y 12 paquetes de panes para pancho, por lo tanto es cierto.

Hello can anyone give me the step by step answer?
NISA [10]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 8, - 42 ) and (x₂, y₂ ) = (- 3, - 17 ) ← 2 ordered pairs from the table

m = \frac{-17-(-42)}{-3-(-8)} = \frac{-17+42}{-3+8} = \frac{25}{5} = 5

The line crosses the y- intercept at (0, - 2 ) , then

y = 5x - 2 → C

After Friday's football game, Megan and her friends go out for ice cream. They share the Mega Mountain sundae and finish the who
Natalija [7]

Answer:  c=  $( 5 x 5.20)

Step-by-step explanation:

Given: Total people =5

Money paid by each person = $5.20

Total cost of the sundae = (Number of people )  x (Money paid by each person)

Total cost of sunday : c= 5 x ($5.20)

i.e.Total cost of sunday = $(5 x 5.20)

i.e.Total cost of sunday = $ 26

Hence, the required equation to represent the total cost (c) of the sundae:

 c=  $( 5 x 5.20)
