Answer 1
Answer: Since you are not distributing at all, you can ignore the parenthesis :)

When ignoring the parenthesis your equation is

Answers

Answer:

<1 = 95

<2 =85

Step-by-step explanation:

<1 = 95

They are alternate exterior angles and alternate exterior angles are equal when the lines are parallel

<1 + <2 = 180  since they form a straight line

95+ <2 =190

Subtract 95 from each side

95-95+<2 =180-95

<2 =85

there are 118 boys and 121 girls signed up for a volleyball league. The coaches first make teams of 9 players and then assign any remaining players to make some of the teams have 10 players.how many teams of 10 players. how many teams of 9 players

Answers

The number of nine-players team= 21 teams.

The number of ten-players team= 5 teams.

Step-by-step explanation:

step 1: The total players signed up for a volleyball league= 118 boys+121 girls= 239 players.

step 2: The coach first makes a 9 players team= 239-9= 230 members

In this stage, the number of 9 players-team is one.

step 3: The remaining 230 players cannot be divided equally into 9 players, since 230 is not divisible by 9.

step 4: Find the number within 230 that is divisible by 9 as a whole. Check for easy number (9*20= 180 is within 230)

Therefore, 230-180= 50 players are remaining.

In this stage, the number of 9 players-team= 1+20= 21 teams with 9-players.

The number of 10 players-team= 50 players/10= 5 teams with 10-players.
