18 - 7x = -20.5

Subtract 18 from each side:

-7x = -38.5

Divide both sides by -7:

x = -38.5 / -7

x = -5.5 = 5 1/2

Answer:

D. 5 1/2

Step-by-step explanation:

18-7x=-20.5

Subtract 18 from each side

18-18-7x=-20.5-18

-7x = -38.5

Divide each side by -7

-7x = -38.5/-7

x =5.5

In fraction form

x = 5 1/2

The formula C=5/9(F−32) can be used to convert temperature from Celsius (C) to Fahrenheit (F). The highest temperature ever reco
Softa [21]

Answer:

57 °C.

Step-by-step explanation:

The formula that is used to convert temperature from Celsius (C) to Fahrenheit (F) is given by :

C=\dfrac{5}{9}(F-32) ...(1)

If T = 134° F, we need to convert the temperature in Celsius.

Put F = 134, in equation (1)

C=\dfrac{5}{9}(134-32)\\\\=\dfrac{5}{9}\times 102\\\\=56.66^{\circ} C\\\\\text{or}\\\\T=57^{\circ} C

So, the temperature on that day is 57 °C.

Simplifique a expressão 10ny-10x+10ny+10y
IRISSAK [1]

Responder:

10 (2ny- (x-y))

Explicación paso a paso:

Dada la expresión 10ny-10x + 10ny + 10y, para simplificar la expresión, se deben seguir los siguientes pasos;

Paso 1; Separa la expresión en términos similares

= 10ny-10x + 10ny + 10y

= (10ny + 10ny) - (10x + 10y)

Paso 2: Factoriza los valores comunes en ambos paréntesis

10ny (1 + 1) - 10 (x-y)

= 10ny (2) - 10 (x-y)

= 20ny - 10 (x-y)

Factoriza nuestro valor común en ambos términos:

= 10 (2ny- (x-y))
