Add the fractions together to find the portion who like basketball, soccer and football.

=1/3 + 1/8 + 5/12
need a common denominator (24)

=8/24 + 3/24 + 10/24
=21/24

simplify by 3
=7/8 like basketball, football & soccer

7/8 is the total for basketball, soccer and football. If 8/8 represents the whole class, then subtract 7/8 from 8/8 to find the number who like baseball.

=8/8 - 7/8
=1/8 of the remainder likes baseball


ANSWER: 1/8 of the students like baseball

Hope this helps! :)

Set up the equation to solve for x
My name is Ann [436]

The three inside angles of a triangle need to equal 180 degrees.

Add the 3 equations together and set to equal 180:


7x+4 + 5x+3 + 2x+5 = 180

Simplify by combining the like terms:

14x + 12 = 180

Subtract 12 from each side:

14x = 168

Divide both sides by 14:

x = 168/14

x = 12

What is the simplified form of each expression?
White raven [17]
<h2>~<u>Solution</u> :-</h2>

According to the given question, we have to find the simplified form of the given expressions. Here, we have been given;

<h3>★ <u>Equation</u> 1 :-</h3>

\sf{(6 + 3)2 - 4}

\leadsto \sf{(9)2 - 4}

\leadsto \sf{18 - 4}

\leadsto \bf \red{14}

  • Hence, (6 + 3)2 - 4 is equals to 14.

\\

<h3>★ <u>Equation</u> 2 :-</h3>

\sf{23 + (14 - 4) \div 2}

\leadsto \sf{23 + (10) \div 2}

\leadsto \sf{23 + 5}

\leadsto \bf \red{28}

  • Hence, 23 + (14 - 4) ÷ 2 is equals to 28.
