PLZ HEL I WILL GIVE 35 PTS An athlete is logging practice time for 3 weeks. If the athlete practices 1 5/6hours the first week, 5 6/7hours the second week, and 3 2/3hours the third week, what is the average weekly practice time? Write the solution as a mixed number or a fraction in lowest terms.

1 is c

2 is a

3 is a

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c
