Third angle = 180 - (6x+7) - (10x-3)
= 180 - 6x - 7 - 10x + 3
= 176 - 16x
just minus the sum of triangle by the 2 angles and you're left with the 3rd one
Population mean = (7+8+6+6+6+4+4+1+2+7+6+1+1+1+3+3+5+4+5+7) / 20 = 87/20 = 4.35 <==
sample mean = (4+5+7) / 3 = 16/3 = 5.33 <==
Answer: 30
Step-by-step explanation:
3 x 30 = 90
Hope this helps!!
X + x +8 = 32
2x + 8 = 32
2x = 24
x = 12
So gerardo has won 12 and jenny has won 20
4x^2+23x-72=
4x(x+8)-9(x+8)=
i got dis 4 yo answer and it is (x+8)(4x-9)
hope dis helped
