Answer:
The mean weight of four members of the wrestling team is 160 pounds.
Three of them have weights of 125, 183, and 169 pounds, the remaining one has weight a.
=> (a + 125 + 183 + 169)/4 = 160
=> a = 160 x 4 - 125 -183 - 169 = 163
=> Option C (163 pounds) is correct.
Hope this helps!

Looks fishy to me, the way this problem combines <, = and > symbols.
But anyway. Subtract 3x from both sides. You'll get
5 < x = 2 > 0 2 > 0 is true, but that's a different type of math problem (true or false). If you decide to substitute '1' for 2 > 0, then the "1" says "TRUE."
Then 5 < x = true, so you must find x values that are larger than 5.
That would be (5, infinity)
Please go back and ensure that you have copied down the original problem exactly as it appears.
Answer:
t=1
Step-by-step explanation:
16-2t=5t+9
