x = x equals StartFraction 20 Over 3 EndFraction is approximately 6.67. ≈ 6.67
She will have to win 7 more games to have a 70% winning record.
How many more games will Aditi have to win to have an 80% winning record?
The linear equation that models this is .
Aditi would have to win more games to have an 80% winning record.

Respuesta :

The linear model is 12 + x = 0.80(20 + x)

Aditi would need to win is 20.

How many more games does Aditi have to win?

Given this linear model: 12 + x = 0.80(20 + x)

Take the following steps in order to determine the value of x:

Expand the bracket : 12 + x = 16 + 0.8x

Combine like terms: 16 - 12 = x - 0.8x

Add similar terms: 4 = 0.2x

Divide both sides by 0.2 : 4/ 0.2

x = 20
