Jojo spends t minutes practicing the guitar. He spends 20 minutes less than twice that amount of time doing homework. Which expression shows the number of minutes Dion spends doing homework?

Respuesta :

Parrain

Answer: 2t - 20

Step-by-step explanation:

Jojo spends t minutes doing homework.

He then spends 20 minutes less than twice that amount of time doing homework.

For homework therefore, let us breakdown the time spent:

  • Spends twice the amount of time = 2t
  • Spends 20 minutes less than twice = 2t - 20

When doing homework, Jojo therefore spends:

= 2t - 20
