What are you trying to find? y?x?..???
Answer:
The correct answer is: 
Step-by-step explanation:
As stated in the question that x represents the number of minutes his <em>normal</em> commute takes. Here the keyword is normal; in the <em>normal</em> commute, Ken takes side streets instead of the toll road.
However, in this scenario, we have to come up with the equation that takes Ken's commute via <em>toll road</em>.
Ken can travel 3 times faster by taking the toll road (Given), which can be represented in the mathematical terms in terms of x as follows:

<em>Without considering Ken getting late, </em>the equation would become the following:
--- (A)
<em>As Ken is leaving late</em>, we have to incorporate that time as well by <em>adding</em> it in the aforementioned equation (A).
In this case, it's 20 minutes; therefore, the equation (A) will become:

Hence, the correct answer is
.
Answer:
Her deduction is 10%, or 0.85
Step-by-step explanation:
Answer:
x + y = 64
x + 10 = y
Step-by-step explanation:
Since it isn't asking for the solutions, I won't solve.
let y represent drama students, and x represent the yearbook students.
We know that DS (drama students) plus YS (Yearbook students) equals 64 students in total. To write this mathematically you would write x(YS)+ y(DS) = 64 (Students in total) except just <em><u>x + y = 64</u></em>.
The second part of this system explains what y is.
We know that the drama club has 10 more students than yearbook students, so YS plus 10 equals the amount of DS. To write this mathematically you would write <em><u>x + 10 = y</u></em>.
Combine the two systems by writing
x + y = 64
x + 10 = y
<em>P.S. Let me know if you need the system solved.</em>
