Can anyone help me with this? is equations of lines.

vladimir2022 [97]

Answer:

x=16

Step-by-step explanation:

y = 1/2 x -3

Let y =5

5 = 1/2 x -3

Add 3 to each side

5+3 = 1/2 x -3+3

8 = 1/2x

Multiply each side by 2

8*2 = 1/2x*2

16 =x

A pergunta não está bem formatada. No entanto, pelo que parece óbvio

Responda:

3 horas

Explicação passo a passo:

Fração de hora gasta por sessão = 3/4 horas por sessão

Se o exercício for feito apenas aos domingos

Número de domingos por mês = 4

Portanto, número de sessões = 4

Fração de horas por sessão * Número de sessões

3/4 * 4 = 3 horas

Portanto, 3 horas são dedicadas ao exercício por mês
