7+3t -t
------- = ----- is the relevant equation here. We don't ask, "What is 7+3t over
4 8 -t over 8," but rather "Solve the following equation for t."
Cross multiplying, 56 + 24t = -4t
-56
Then: 28t = 56, and t = ------ = -2 (answer)
28
The solution to "<span>What is 7+3t over 4 = -t over 8" is t = -2.</span>
Answer:
c = 55 . . . . (no units for cost are given in your problem statement)
Step-by-step explanation:
"t is the number of tickets" and "Marci bought 20 tickets", so we conclude t=20. Putting that value into the equation and doing the arithmetic, we find ...
c = 2.75·20 = 55

Step-by-step explanation:
angle is x
supplement is 180-x
x+96=180-x, since it is 96 less than its supplement
2x=84
x=42
180-x=138
The angle is 42 degrees.
Answer:
x = 11.5
