Answer:
39.15
Step-by-step explanation:
For area you just do 4.5 times 8.7 and then you get 39.15
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

44 because you divide 220 by five because it’s 4 times as many and then add one for the employees. Try it! 44 is right and 176 for the listeners of you need that too
Answer:
We have the equation:
(ax^2 + 3x + 2b) - (5x^2+bx-3c)= 3x^2 - 9
First, move all to the left side.
(ax^2 + 3x + 2b) - (5x^2+bx-3c) - 3x^2 + 9 = 0
Now let's group togheter terms with the same power of x.
(a - 5 - 3)*x^2 + (3 - b)*x + (2b + 3c + 9) = 0.
This must be zero for all the values of x, then the things inside each parenthesis must be zero.
1)
a - 5 - 3 = 0
a = 3 + 5 = 8.
2)
3 - b = 0
b = 3.
3)
2b + 3c + 9 = 0
2*3 + 3c + 9 = 0
3c = -6 - 9 = -15
c = -15/3 = -5
Then we have:
a = 8, b = 3, c = -5
a + b + c = 8 + 3 - 5 = 6
