Answer:
Step-by-step explanation:
Step 1. Calculate the common ratio
a₁ = 250
a₂ = 100
a₃ = 40
a₄ = 16
The common ratio is
a₃/a₂ = 40/100 = 0.4
Step 2. Write the formula for the series
The formula for the nth term of a geometric sequence is
aₙ = a₁rⁿ⁻¹
Thus, the formula for the series is
Statement: If a number is even, then it is divisible by 2.
Converse: If a number is divisible by 2, then it is even.
The converse is true.
Answer:
x = - 7
Step-by-step explanation:
8x - 2 = -9 + 7x (add 2 to both sides)
8x - 2 + 2 = -9 + 7x + 2
8x = 7x - 7 (subtract 7x from both sides)
8x - 7x = 7x - 7 - 7x
x = - 7
