It's A.
Rae made the error when she added 7.
the equation should be:
<span>-14 - 7 = 7x + 7 - 7 </span>
The two variables are time (x) and distance (y)
And the answer is they will meet after 1 mile
The function of the aunt and uncle is y=25x+5
The function of yourself is y2=30x
Since you want to know when you’ll meet, you just resolve y=y2 or 25x+5=30x
Wich will be x=1 so 1 mile
Thanks for asking your question!

Answer:
<u>7y +2x</u>
Let x = the number of weeks
Hope this helps!
Answer: 7/8
Cos2x has 3 formulas, Sinx is given in the question, we should use the formula with sinus. I guess that's the solution.
Step 1: Line up the equations so that the variables are lined up vertically.
Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same.
Step 3: Subtract the two equations.
Step 4: Solve the one variable system.
Step 5: Put that value back into either equation to find the other equation.
Step 6: Reread the question and plug your answers back in to check.
