Answer:
B. 20÷10=2
Step-by-step explanation:
Well , A and C can not answer 2×10 = 20 , whatever , even have not make the equation correct .
Correct A. 2÷10=2/10=0.2 Even have a correct, still can not answer why 2×10 = 20
_______________________________ (1). 2÷10 ≠ 20 ( Proof )
B. 20÷10=2 This a correct answer (1). 20÷10 = 2 ( Proof )
_______________________________ ↓
_______________________________ (2). 20 = 2×10 ( Proof )
_______________________________ ↓
_______________________________ (3). 20 = 20 ( Proof )
it answered why 2×10 = 20
Correct C. 20×10 = 200 Still Wrong answer
_______________________________ (1). 20×10 ≠ 20 ( Proof )
Hope that will help you to understand
Find an explicit formula for the arithmetic sequence 12, 5, -2, -9,...12,5,−2,−9,...12, comma, 5, comma, minus, 2, comma, minus,
Andrew [12]
Answer:
A(n) = 19 - 7n
Step-by-step explanation:
12, 5, -2, -9,...
First term, a = 12
Common difference, d = a2 - a1
a2 = 5
a1 = 12
Common difference, d = a2 - a1
= 5 - 12
= -7
d = -7
A(n) = a + (n - 1)d
A(n) = 12 + (n - 1) -7
= 12 + (-7n + 7)
= 12 - 7n + 7
= 12 + 7 - 7n
= 19 - 7n
A(n) = 19 - 7n
