Use directly proportional.
y=kx
20=18k
k=18/20
k=0.9

y=0.9 x 837
y=753.3

753.3 is minutes so change to hours is
753/60=12.55
12.55+0.30=12.85
12.85=13.25hours

Answer: 13.25hours

Rzqust [24]

The number of students that are on the track team are 18.

The number of students that are on the baseball team are 15.

<h3>What are the linear equations that represent the question?</h3>

a + b = 33 equation 1

a - b = 3 equation 2

Where:

  • a = number of students that are on the track team
  • b = number of students that are on the baseball team

<h3>How many students that are on the baseball team?</h3>

Subtract equation 2 from equation 1

2b = 30

Divide both sides by 2

b = 30/2 = 15

<h3>How many students that are on the track team?</h3>

Subtract 15 from 33: 33 - 15 = 18
