The expressions D, E, and F represent a correct solution to the equation.
Step-by-step explanation:
Step 1:
First, we need to solve the given equation and find the value of x which satisfies the equation.


So the value of x for the given equation is -0.666.
Step 2:
Now we evaluate the values of the six given options to see which ones have an x value of -0.666.
A. 
B. 
C. 20 -6 -4 = 20 - 10 = 10.
D. 
E. 
F. 
So the options D, E, and F represent a correct solution to the given equation.
Answer: $74
<u>Step-by-step explanation:</u>
Let C represent the cost of a coach ticket
Let B represent the cost of a business ticket
Washington: 150C + 50B = 18,450
NY City: 170C + 100B = 27,280
Solve the system using the Elimination method:
-2(150C + 50B = 18,450) → -300C - 100B = -36,900
1(170C + 100B = 27,280) → <u>170C + 100B = 27,280 </u>
-130C = - 9,620
<u> ÷ -130 </u> <u> ÷ -130 </u>
C = 74
I don’t really know but it’s lost like the answer and yea
