Answer:
x = 3
y = 3/2
Step-by-step explanation:
look at the hangers to form an equation:
x + x + x + 3 + 3 + 3 = x + x + y + y + y + y
simplify
3x + 3 = 2x + 4y
x + 3 = 4y
x = 4y - 3
you also know that
x + x = y + y + y + y
2x = 4y
substitute x = 4y - 3 into this equation ^
2x = 4y
2(4y - 3) = 4y
8y - 6 = 4y
4y = 6
y = 6/4
y = 3/2
2x = 4y
2x = 12/2
2x = 6
x = 3

Answer:
5
Step-by-step explanation:
5 > 0 (True)
Plug in 5 for t in the equation.
t² - 25 = 0
(5)² - 25 = 0
(5 * 5) - 25 = 0
(25) - 25 = 0
0 = 0 (true).

Answer:
39062.5
Step-by-step explanation:
-2+-10+-50+-250
-10/2=-250/-50 = 5
sum of the geometric sequence
Sₙ = arⁿ⁻¹ /r-1 a=-2, r = 5
S₈ = -2(5)⁸⁻¹/(5-1) = 2(5⁷)/4 = 2(78125)/4= 78125/2= 39062.5
S₈=39062.5
