There would be 10 mens out of the 20 because since 5 is a half of 10 then u could predict that there is a half of people that are mens in the 20 people.
Let x = the vertex angle so 30 + x = the base angle.
The sum of the three angles = 180 degrees. Set up an equation then solve.
x + 30 + x + 30+ x = 180
3x + 60 = 180
Subtract 60 from both sides
3x = 120
Divide both sides by 3
x = 40 => => Vertex Angle
x + 30 = 70 => => Base Angles
Answer:
D 36
Step-by-step explanation:
<em>Write the information algebraically</em>
c = 3a
c + a = 48
c = children, a = adults
<em>In the second sentence (in bold), we can replace c with 3a</em>
c + a = 48 → 3a + a = 48
<em>Simplify</em>
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
<em>We can then substitute or plug in a = 12 into the original equation:</em>
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
<h3>There are 36 children</h3>
The square root of 5 is 2.23 so it would be closer to 2
Answer:
5x-1y-11y
Step-by-step explanation:
3x+4y-3xy+5x+3y-2xy-2x+y-3xy+10x-9y-8xy
2x+5x+4y+3y-3xy-2xy-2x+10x+y-9y-3xy-8xy
7x+7y-5xy-12x-8y-11xy
7x-12x+7y-8y-11xy
-5x-1y-11xy
