X+ y = 44
x - y = 6
—————
2x = 50
x = 25
y = 44-x = 19
Answer:
x ≤ 2
Step-by-step explanation:
Isolate the variable, x. Note the ≤ sign, treat it like an equal sign, what you do to one side, you do to the other.
First, subtract 3 and x from both sides:
2x (-x) + 3 (-3) ≤ x (-x) + 5 (-3)
2x - x ≤ 5 - 3
Simplify:
2x - x ≤ 5 - 3
x ≤ 2
x ≤ 2 is your answer.

Step-by-step explanation:
the sequence is a geometric sequence
simply use the formula:
t(n) = a * (r)^n-1
where n = 8, a = 27, r = 4/3
