Answer:
A: I think it's A because you need to graph both equations
Answer:
Step-by-step explanation:
2x+x+3(2x)=63
3x+6x=63
9x=63
9x/9=63/9
X=7
2x=14
3(2x)=42
Answer:
Step-by-step explanation:
(r/s)(x) is the quotien of r(x) = 3x - 1 and s(x) = 2x + 1:
r 3x - 1
(-----)(x) = ----------
s 2x + 1
Answer:
Step-by-step explanation:
A)1st pair: ∠HKJ ,∠JKG 2nd pair: ∠HKE,∠EKF
B)Verticle angle:∠HKE and ∠GKF
C) 4x+5+41=180
4x+46=180
4x=134
x=33.5
D)4x+36=90
4x=90-36
4x=54
x=13.5
E) x+x-4=180
2x=184
x=92
To calculate the remaining number of teams, use the sequence formula:
a(n) = a(1)Rⁿ-¹
Where a(n) and a(1) are the nth and first terms. R is the factor. Therefore, 24 teams is valid value.
After 5 rounds :
a(5) = 128*(½)⁴
a(5) = 128/16 = 8
8 teams are remained.
