Answer:

<em>NI = 3 cm</em>

Step-by-step explanation:

The side splitting theorem allows you to set up this proportion.

\dfrac{AT}{AR} = \dfrac{TN}{NI}

\dfrac{8}{2} = \dfrac{12}{NI}

Cross multiply.

8NI = 2 *12

8NI = 24

NI = 3

Mark scored 17 points for the home team in a basketball game. His teammates as a group scored p points. As a team they scored 46
ki77a [65]

Answer:

Equation:

17 + p = 46

His teammates scored 29 points

Step-by-step explanation:

We know that Mark scored 17 points and that the entire team scored 46.

Mark's 17 points added to the team's p points will give us a total of 46 points

p = points of his teammates

17 + p = 46

if we want to know how many points his teammates scored we simply have to clear p and solve

17 + p = 46

p = 46 - 17

p = 29

his teammates scored 29 points
