Now David wants to solve the equation 4000x - 8000 = 16,000.
a.
What easier equation could he solve instead that would give him the same
solution? (In other words, what equivalent equation has easier numbers to
work with?)
b.
Justify that your equation in part (a) is equivalent to 4000x - 8000 = 16,000
by showing that they have the same solution.
c.
David's last equation to solve is 180 + 180 = 186 . Write and solve an
equivalent equation with easier numbers that would give him the same
answer.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
