The football team has 30 more members than the basketball teams. If each group had 10 more members, the ratio of their membership would be 3:2. How many members are in each group? Write your answer as football x basketball yHELP PLEASE !

Answers

x = y + 30 (I)

$(x + 10)/(y + 10) = (3)/(2)$

2x + 20 = 3y + 30
2x - 3y = 10 (II)
______________________________
2(y+30) - 3y = 10
2y + 60 - 3y = 10
-y = -50
y = 50

x = y + 30
x = 50 + 30
x = 80

Football team has 80 members, basketball team has 50 members.

(3x - 4)(-6x + 5)

F: 3x*-6x = - 18x^2

O: 3x * 5 = 15x

I: - 4*-6x = 24x

L: -4 * 5 = -20

-18x^2 + 24x + 15x - 20

-18x^2 + 39x - 20

Answers

Answer:

The answer to your question is m = 64

Step-by-step explanation:

Equation

$(m)/(4) - 6 = 10$

Process

1.- Add 6 to both sides

$(m)/(4) - 6 + 6 = 10 + 6$

2.- Simplify

$(m)/(4) = 16$

3.- Multiply both sides by 4

$4(m)/(4) = 16(4)$

4.- Simplify and result

m = 64
