Soloha48 [4]
I don't think you use a fraction. You multiply .6666 by 72 which equals 47.9952 or rounded 48. :)

In their last game, the school football team scored an equal number of points in each of the first three quarters, then 14points
Ksenya-84 [330]

Answer:

10 points

Step-by-step explanation:

Points scored in each of the first 3 quarter = x

Total points scored in the first 3 quarter = x + x + x

= 3x

Points scored in the fourth quarter = 14

Total points scored = 44 point

Total points scored = Total points scored in the first 3 quarter + Points scored in the fourth quarter

44 = 3x + 14

Subtract 14 from both sides

44 = 3x + 14

44 - 14 = 3x + 14 - 14

30 = 3x

Divide both sides by 3

x = 30/3

= 10

x = 10 points

Points scored in each of the first 3 quarter = x = 10 points

The school football team scored 10 points points in the first quarter
